9/16" x 3.0" Bolt Kit

9/16-18 x 3" Grade 8 bolt

2 washers and an all metal lock nut.

Approximate torque spec = 146 ft-lbs

NOTE : This kit uses a Top Lock - it will NOT screw on by hand. Start by hand, then use torque wrench.

Uniquely shaped threads provide a vibration resistant friction fit, so the nut stays put. These all metal locknuts withstand higher temperatures than nylon insert locknuts. Top thread section is deformed to create two or three locking zones; they start easily by hand, then must be wrenched into final position. Grade C equivalent to Grade 8. IFI-100/107 Grade C. ANSI B1.1 UNC or UNF Class 2B thread requirement. Zinc plating, retards the corrosion rate in a normal atmosphere.
