Description
Overview:
Metric Nylon Insert Locking Nuts in M20 are hexagonal steel nuts with a captive nylon collar that provides a prevailing torque lock on the threads. The bright zinc-plated finish offers dependable corrosion resistance for indoor and outdoor use. Designed for securing M20 bolts and studs, they are widely used on construction plant, trailers, agricultural kit, and garden machinery such as mowers and compact tractors. The nylon insert grips the male thread to resist loosening from vibration and shock loads, helping maintain clamp force over time. Suitable for general assembly, maintenance, and repair, these nuts pair well with HT bolts, carriage bolts, and threaded rod. Supplied in a pack of 10 to support multiple fixes or full fastener replacements on one job.

Suitable for routine servicing, refurbishments, and new builds where a secure, re-torqueable fastening is required.
Also known as:
Often referred to as nylocs, nylon-insert nuts, prevailing torque nuts, self-locking hex nuts, insert lock nuts, stop nuts, or locknuts with polymer collar. These terms describe the same locking principle using a nylon ring to resist loosening under vibration and dynamic loads.
