Stainless steel 18-8 nylon insert locknuts

A Stainless Steel (SS) 18-8 Nylon Insert Locknut is a high-quality, durable fastener that offers greater corrosion resistance than Grade 8, Grade C, or Zinc alternatives, often used in moisture-exposed, exterior, or corrosive environments 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 stainless steel construction provides reliable performance in demanding environments while maintaining a clean, polished appearance.
