Mechanical and Material Requirements for SAE J2283 One Piece Wheel Nuts

Developed by the Society of Automotive Engineers (SAE), the SAE J2283 standard describes chemical, metallurgical and mechanical requirements for one-piece passenger car and truck anchor lug nuts with tapered or spherical nut sockets for certain dimensions. The test method described in this standard is for typical wheel nuts. Special applications, such as nut material and configurations, require special conditions that must meet the load values ​​in the standard.

Wheel nuts or coupling nuts allow the wheels on the vehicle to be fixed to the body of the vehicle. Car lug nut, which is among the main fasteners, is widely used in different vehicles such as automobiles, trucks, vans, buses, tractors, agricultural and construction machinery. Essentially, lug nuts secure the wheel hub to the threaded wheel studs on the vehicle's axle, keeping the wheel fixed in place and properly centered on the axle. In general, wheel nuts are made of chrome-plated steel. Chromium is used to provide corrosion resistance. However, titanium or anodized aluminum lug nuts are typically produced for racing cars.

One-piece lug nuts are used by automobile manufacturers all over the world to hold wheels steady to a vehicle.

The lug thread type varies between car makes and models. Examples of common metric threads include:

• M10×1,25 mm pitch
• M12 (1,25, 1,5 or 1,75 mm pitch, M12x1,5 mm is most common)
• M14 (1,25, 1,5 or 2mm pitch, M14×1,5mm is most common)
• MXNXX × 16 mm

Essentially, the SAE J2283 standard covers chemical, metallurgical and mechanical requirements for the following dimensions:

• M10x1.25, M14x1.5 ve M14x2.0 9/16-18
• M12x1.25 ve M12x1.5 1/2-20

Wheel nuts are produced in different ways. Alloy and forged wheels generally require special lug nuts to fit in the mounting holes. Therefore, when replacing rims, it is necessary to purchase a new set of lug nuts.

Our organization, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, SAE J22Within the scope of the 83 standard, it also provides testing services for mechanical and material requirements for one-piece wheel nuts.
