Wheel Nut Seat Strength
STANDARD published on 1.1.2026
Designation standards: SAE J2315
Publication date standards: 1.1.2026
Country: American technical standard
Category: Technical standards SAE
The purpose of this test is to evaluate the axial strength of the nut seat of wheels intended for use on passenger cars, light trucks, and multipurpose vehicles. In addition, a minimum contact area is recommended to ensure enough strength for the rotational force in tightening a nut against the nut seat. While this test ensures the minimum strength of the nut seat, the wheel must also have a degree of flexibility. This flexibility, as well as bolt tension, are important to maintain wheel retention.
