Seachoice Stainless Steel Nylon Insert Locknut Nut

Seachoice stainless steel nylon insert locknuts (also called nyloc nuts, lock nuts or self-locking nuts) are marine-grade fasteners for applications that need a secure connection that resists loosening. They work well on boats, trailers, docks and other places exposed to moisture and vibration.

Key Features:

• Stainless steel construction resists corrosion and rust in wet and marine environments
• Nylon insert grips the bolt threads to help keep the nut from backing off under vibration
• Self-locking design means no extra lock washer or thread-locking compound is needed
• Hex body fits standard wrenches and sockets for easy installation
• Multiple sizes are available to match common bolt and machine screw threads

Use these locknuts with compatible stainless steel bolts and screws for a durable, long-lasting fastening solution. For best results, match the nut thread size and pitch to the mating fastener. Nylon insert locknuts are intended for limited reuse, so replace them if the insert has worn and no longer grips firmly.
