Value Collection 812206PS Hex Lock Nut M20x1.5 Class 8

Product Description

The VALUE COLLECTION 812206PS is a metric hex lock nut with a nylon insert locking mechanism, designed for general-purpose fastening applications requiring reliable vibration resistance. Built to Class 8 steel with a zinc finish, this nut meets DIN 985 standards and carries an M20x1.5 thread size with right-hand threading. The nylon insert deforms around the mating thread to create a prevailing-torque lock, eliminating the need for additional locking hardware. Width across flats measures 30 millimeters, and height measures 20 millimeters. Installed by mechanics, millwrights, pipefitters, and general trade workers wherever metric fasteners are specified.

This nut is suited for use in mechanical assemblies, structural connections, and equipment installations that follow metric fastener standards. Its zinc finish provides basic corrosion resistance in moderate environments. Typical applications include machinery mounting, frame assemblies, and industrial equipment where a secure, re-torqueable lock nut is required. The single-piece nylon insert design makes it straightforward to install with standard metric tooling. This nut is packaged as a single unit.

Compatibility

Designed as a standard DIN 985 metric hex lock nut for use with M20x1.5 threaded bolts and studs in metric fastener assemblies.

Installation Notes

Install and remove using a 30 millimeter metric wrench or socket. Power down and de-energize any equipment before servicing fasteners in electromechanical assemblies. Nylon insert lock nuts are intended for one-time installation; reuse after removal is not recommended as the nylon insert loses locking effectiveness after initial seating. Follow applicable equipment manufacturer torque specifications and relevant mechanical codes for the application.
