Road Vehicles—Wheels for Commercial Vehicles and Multipurpose Passenger Vehicles—Fixing Nuts—Test Methods
- Ground Vehicle Standard
This SAE Recommended Practice is written to test the wheel attachment system which includes both externally and internally threaded fasteners. Therefore, the proof load values are calculated numbers for the externally threaded member, or based on actual industry test data.
Metric values for proof load have been included in this document. In most other countries, the common units for proof load are newtons (N).
In Table 2, Test Torques and Tensions, the initial torque value A was chosen as a value just under the minimum recommended torque by SAE J267. The initial tension value B is the estimated minimum tension required to provide proper nut performance. The final tension values D are maximum values set up so as not to exceed the proof load of the externally threaded fastener.
This SAE Recommended Practice has been updated to include Static and Dynamic Torquing to facilitate different kinds of equipment.

The responsibility of the Truck and Bus Wheel Committee of the Truck and Bus Brake and Advanced Driver Assistance Systems Steering Committee is to initiate, develop, review and approve the recommended practices, standards, and information reports related to hubs, wheels and the wheel mounting systems of buses, trucks and tractor-trailer combinations intended for highway use. The Wheel Committee is constituted so as to be aware of other SAE wheel activity and to prevent duplication of effort.
