What size are Mini Cooper lug nuts?
Thread Size: M12 x 1.5. Hex Size: 17mm.
What is the torque for 1/2 20 lug nuts?
Based on your studs being 1/2 inch, your wheels being 15 inches in diameter, and your lug nuts being coned you would want to torque your lug nuts to 90-120 ft lbs of torque. It’s recommended that you tighten them in a star pattern.
What is the torque spec?
Recommended torque specifications are unique for each type of vehicle. By definition, torque refers to the amount of rotational force at the point of application. When attaching a wheel to a vehicle, torque specifications are the amount of force recommended on the hardware to ensure proper installation.
How do you measure torque on lug nuts?
Attach each lug nut by hand, and then use a manual torque wrench to tighten until you hear the ‘click’ sound that indicates you’ve reached the right amount of torque. The number—usually in the 75-100 lb-ft range—should be easy to locate in your vehicle’s owner’s manual.
What size lug nuts are on a 2012 Mini Cooper?
Mini Cooper 2012, Silver Cone Seat Lug Bolts by Dorman®. Thread Size: M14 x 1.25. Hex Size: 17 mm. Thread Length: 0.87′.
Can you over tighten lug nuts?
Excessively tightened lug nuts can strip the threads, distort brake rotors, damage the wheel, and possibly shear off the lug stud. Insufficiently tightened lug nuts can come loose, with catastrophic consequences.
How much torque does it take to break a lug nut?
An impact wrench with a minimum of 500 ft-lbs torque is required to remove lug nuts. What tool do you use to remove lug nuts? An impact wrench works best, either battery-powered or air-operated.
What is the torque for a 13/16 lug nut?
just about any steel wheel lug nut is a minimum of 85 lb. -ft. This includes a good majority of Lighter utility/cargo/boat trailers as well as alot of vehicles and light trucks.
What size are BMW lug nuts?
17mm is the standard BMW bolt head size so you won’t have to buy extra sockets. The seat is a standard diameter but may not fit all brands of wheels. If you have a small diameter bolt bore on your wheels, try our compact 19mm wheel nuts.

Caution! Conflicting wheel lug nut torque specs!
As a result of bringing my 2013 Countryman to America’s Tire for a free tire rotation today, I was surprised to see that the invoice said that the required torque for the wheel lug nuts is 90 lb/ft. I informed him that the 2nd generation MINIs should have a torque of 100-105 lb/ft. I informed him that the torque specification for the 1st generation MINIs (r50, r52, and r53), which use 12mm nuts, is really 90lb/ft (vs 14mm for the 2nd gen). He stated that he must follow the instructions provided by their computer (interestingly, the computer DID display 100lb/ft for the Clubman ONLY, which makes no sense).
- Using the owners manual in my glovebox, I discovered that the torque specifications are not written in my 2013 Countryman paper handbook, for whatever reason.
- As a result, I requested that he contact a nearby MINI store for confirmation.
- Once again, I contacted with the MINI service adviser, and I requested that he double-check the FACTORY SERVICE MANUAL for me.
- Finally, I went to the MINI website and discovered links to pdfs of the 2nd generation MINI owners manuals (there are distinct ones for ‘Hardtop/Club,’ ‘Countryman/Paceman,’ and ‘Coupe/Roadster/Convertible’ models).
- ‘ 103.3lb/ft ‘ was printed directly on the front of each one of them!
- Following a phone discussion with management, I showed the America’s Tire guy what I had discovered, and after some more time on the phone, he ultimately torqued my lugs to 105lb/ft.
- I left a voice mail for the MINI service adviser, informing him that the owners manuals had been discovered on ‘103.3lb/ft.’ Unsurprisingly, he has not answered my phone call as of this writing.
There is a significant gap between 85 and 105 points. Despite the fact that I doubt a wheel would have come off under typical driving conditions, you never want to take any chances with this kind of equipment or machinery.
Wheel Lug Torquing
(Read the article in Spanish.) To ensure proper wheel installation, the wheel-attaching hardware (lug nuts or bolts) must be tightened to the appropriate torque standard for the vehicle’s make, model, and year, as specified by the manufacturer. In most cases, the owner’s handbook for the vehicle will provide torque requirements. To get proper torque, it is necessary to use the proper equipment, methods, and patterns. These will prevent the hardware from becoming overtightened, the fastener threads from becoming stripped, and the studs from becoming stretched.
- Under- or overtightening the hardware that holds the wheels in place can be harmful and dangerous.
- The threads of the fastener should be free of oil, dirt, grit, corrosion, and other contaminants.
- It is critical not to grease the threads or seating of any hardware.
- A change in friction created at the lug seat due to lubrication of hardware threads and seats will result in erroneous torque readings as well as over-torqueing of the hardware.
- If you are installing wheels, we do not encourage the use of impact guns or torque sticks.
- To properly tighten the hardware on some cars, such as Porsches, the use of specific sockets is required in order to prevent the anodized coating from being damaged.
- Some of the variables that might lead to inaccuracy in torque delivery are as follows:
- The type of impact (air, electric, or cordless) that was employed. Battery life (battery power and battery age)
- Air pressure and volume (length of hose and size of fittings)
- And The number of impacts per second
- Internal hammer sizes are as follows: It is possible to utilize extra adapters. Size, weight, and length of the socket
- Grip strength of the operator The magnitude of the impact
- During usage, the angle is applied
A click-type torque wrench cannot be used to ensure that the necessary amount of torque is present while the hardware is being fully tightened with impact guns or torque sticks. While a click-type torque wrench can detect when the desired torque has been attained, it is unable to detect excessive torque. Once you have the proper tools, follow the crisscross sequence (patterns illustrated below) for the number of wheel-attaching hardware points on the vehicle until all of the positions have met the desired torque value.
A repeat installation should be performed in the event that the clamping loads have changed following the initial installation as a result of metal compression/elongation or thermal stresses affecting the wheels while they are breaking in, as well as to ensure that the original installation was accurate.
Loosen and retighten to the specified value in a sequential manner, using the torque protocols mentioned above. If you are unable to locate the car manufacturer’s suggested torque specification, the following information might be used as a reference.
|Hardware Bolt or Stud Size||Typical Torque Range in Ft/Lbs||Minimum Number of Turns of Hardware Engagement|
|12 x 1.5 mm||70 – 80||6.5|
|12 x 1.25 mm||70 – 80||8|
|14 x 1.5 mm||85 – 90||7.5|
|14 x 1.25 mm||85 – 90||9|
|7/16 in.||70 – 80||9|
|1/2 in.||75 – 85||8|
|9/16 in.||135 – 145||8|
2nd Gen – R56 – Cooper – S – Lug nut torque on R56 S?
- 10th of April, 2011301 Ratings:+0/0/-0 I haven’t been able to locate this information. Before rotating my 17-inch wheels, I’d want to find out how much torque should be applied to the lug nuts. Anyone? Thanks

- 8th of June, 2010500NW NCRatings:+0/0/-0 Although this is an old post, the torque specification in the handbook is particular to the steel spacesaver tire. These aren’t your typical alloys. Alloy wheels are far softer than steel wheels and require significantly less torque to avoid galling the seats. I’d tighten to 85 lb-ft and recheck after 100 miles
- I’m presuming the high torque specification is mostly for the thick 14mm bolts, but I might be wrong

Columbus, Ohio-based proprietor of a small bespoke metal manufacturing firm Ratings:+7,632/1/-0 This is an excellent question, and I’ll check the Bentley book after work to see whether the bolt size is indicated. Is it true that all R56s came with 14mm lug bolts? or did that alter shortly after the introduction of the Gen 2 MINI? All Gen 2 MINIs are equipped with 14mm lug bolts. In addition, all 1st Gen vehicles constructed after 07/06 are equipped with 14mm tires. So thicker bolts are associated with more torque? Were the R53 12mm bolts rated at 89 ft/lbs, or were they less?

Ratings:+412/0/-0 The thickness of the bolts is not the most important factor. The amount of torque required to exert enough pressure on the accessible surface area of the threads is determined by the coarseness or fineness of the threads, as well as the pitch of the threads. If you want to know the arithmetic underlying torque specifications, read this white paper on the subject. Analysis of Bolt Torquing Techniques My E36 BMW, which has five 12mm bolts, has a torque specification of 100 N-m. My R53, which has four 12mm bolts, has a torque specification of 120 N-m. The R56 with four 14mm bolts has a torque specification of 140 N-m. (14mm bolts having a 36 percent larger cross-sectional area than 10mm bolts.) I think the R56 also has a finer thread pitch than the R55. BoltsSizeTorque512100412120414140 My engineer brain recognizes a pattern in this situation
- 8th of June, 2010500NW NCRatings:+0/0/-0 All right, fellas. Thank you so much for ‘clearing’ it up. :crazy: Yes, the steel bolts are capable of withstanding the torque. I’ve never had any doubts about it. However, I was under the impression that there was a distinct torque specification for the softer alloy wheels that were sandwiched between them. I could picture the bolts being torqued to the maximum with an aluminum wheel in between them if there were washers / free-spinning seats or a steel ring to which we were fastening. However, in all other cases, no. I’m not trying to cause issues
- I’ve simply noticed that various specifications have been given in manuals for steel and alloy wheels in the past. However, this is not the case for MINIs (as an example, my old BMW 320i)

Wheel Lug Nut Size Guide + Torque Spec Chart
Lug nuts are available in a number of different shapes, seat angles, thread pitches, and wrench types to suit your needs. This buyers guide will walk you through the process of selecting and installing the right lug nuts for your vehicle and/or aftermarket wheels in five straightforward stages.
- Seat type, thread size and pitch, wrenching type, appearance, and torque specifications are all important considerations.
Seating Configuration Making a determination as to what sort of lug nut seat your wheels require is the first step in picking the most appropriate lug nuts for your application. A 60-degree included angle tapered seat lug nut is a relatively popular automobile lug nut style that is used on many different vehicles. When opposed to a shank or mag seat, the tapered seat will aid in the centering of the wheel when the lug nuts are tightened, and it will often result in a truer and more balanced assembly overall.
The 45-degree specification is a centerline angle measurement, which results in a 90-degree included angle in the specification.
It is not recommended to install 45-degree lug nuts on OEM wheels with a 60-degree tapered seat.
Lug nuts are available with a range of seat configurations.
Shank or mag seatlug nuts have a flat seat and, in most cases, a washer is used to prevent the lug nut from rubbing on the wheel.
Avoid ordering a shank diameter that is lower than the size of your wheels since this will most likely result in an assembly that is out of balance and/or not in the proper shape.
These lug nuts are utilized on a limited number of wheels as well as wheel spacers and adapters.
This may be accomplished by taking the outer diameter of the wheel stud threads on your car.
The most often seen thread diameters for lug nuts in SAE sizes are 7/16′, 1/2′, 9/16′, and 5/8′.
Find out how to calculate the thread pitch for your lug nuts.
Measure the length of a one-inch segment with a tape measure and count the number of threads.
The most frequent thread pitch for SAE sizes is 11, 18, and 20 threads per inch, resulting in the most common SAE thread sizes being 11, 18, and 20 threads per inch.
In order to calculate the thread pitch on Metric threads, you must count the number of threads that are included inside a one millimeter piece of the stud’s length.
Exemple: If your part has 10 mm of threads and you have 15 threads in it, that means there are 1.5 threads per millimeter, and the arithmetic looks like this: 15 tenths equals one-fifth.
12 mm x 1.25, 12 mm x 1.50, and 14 mm x 1.50Wrenching TypeHex lug nuts are by far the most prevalent type of lug nut to be found on automobiles.
When the vehicle is in need of care or repair, the wheels may be removed and replaced by any mechanic or tire shop at their convenience.
If you are concerned about theft, you may want to consider investing in a set of wheel locks, which will be discussed in further depth below.
The traditional hex, spline, and hex key are displayed.
In addition to being utilized for anti-theft purposes, one spline drive lug nut per wheel can also be used for what is known as ‘wheel locks.’ Installation and removal of these lug nuts will necessitate the use of a specialized socket.
In the event that one of your spline drive lug nuts is broken or misplaced, having a spare socket on hand is a smart idea.
As a result, they have a smooth outside look, and they are frequently used with wheels that have a very small counter bore in which to accommodate the usage of the lug nut.
It is advantageous to use this type of lug nut since it will not cause any harm to the finish of the lug nuts’ exterior surface when they are installed or removed.
If you have this type of lug nut installed on your vehicle, you will need to have special equipment on hand in case you have a flat while driving.
Open lug nuts are also commonly utilized in racing applications since certain laws specify a specific number of threads that must protrude over the end of the lug nut in order to be legal.
When it comes to racing, double-sided lug nuts are most commonly employed in situations when pit stops must be kept as short as possible to maximize performance.
Lug nuts are available in a number of different colors and finishes.
This results in a highly clean appearance, making them ideal for hot rods, muscle cars, show vehicles, and daily drivers alike.
A large number of open end lug nuts are zinc plated for corrosion protection, however they do not have the high shine quality that is required in particular applications.
Black lug nuts are also available to further personalize the design of your wheels to match your own preference.
We recommend that you use a 1/2′ drivetorque wrench to do this task.
This will ensure that the wheel is correctly seated.
Follow the torque sequence outlined above for your unique lug count to ensure a proper fit. Wheel Specs for lug nut torque Lug Nuts and Wheels are available for purchase.
