14、will be suitable for the attachment of two seat belt assemblies. Bolts shall have a minimum static strength of 40.0 kN (9,000 lbf) when tested with the load applied at 45 to the axis of the bolt as required in the FMVSS 209. In the event of a referee decision regarding the acceptance of a lot of the
15、se bolts, the minimum static load at 45 shall take precedence over other mechanical properties. 4.5.1 Static Load: The static load test required in Federal regulations shall be performed using the procedures and fixtures shown in SAE J140 to simulate the loading applied in service with each style of
16、 bolt. 4.5.2 Ultimate Tensile Strength: determined by 6 wedge test procedure per SAE J429: 7/16-20 UNF and 1/2 -13 UNC bolts: 917 MPa (133 ksi) minimum.
