Product Description

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. IFI 100/107 Grade G. ANSI B1.1 UNC and UNF Class 2B.
