Grade 8 yellow zinc nylon insert locknuts

A Grade 8 Yellow Zinc Nylon Insert Locknut is a high-strength fastener with a yellow zinc-plated finish, offering superior tensile strength over Grade 2 and Grade C alternatives and light corrosion protection, often used in heavy-duty and high-stress fastening applications where vibration resistance is also required.

Nylon insert locknuts have a six-sided nut body with a nylon collar permanently embedded in the top of the nut, designed to grip the threads of a mating bolt or rod and resist loosening from vibration without damaging the fastener. Their six-sided body allows for easy tightening with standard wrenches and sockets, and the high-strength alloy steel construction provides reliable performance in demanding mechanical and structural applications.
