Value Collection A210196 Hex Lock Nut M20 X 2.50 Din 985 10pk

Product Description

The VALUE COLLECTION A210196 is an M20 x 2.50 hex lock nut with a nylon insert locking style, manufactured from 18-8 A2 stainless steel in an uncoated finish. The nylon insert creates interference with the mating thread to resist loosening under vibration and dynamic load conditions. Conforming to DIN 985, this fastener carries a right-hand thread direction and is sized at 20.00 mm in height with a 30.00 mm width across flats. It is suited for general mechanical assembly, structural connections, and equipment fabrication where corrosion resistance and thread retention are required. Sold in a package of 10 per the listed quantity.

This hex lock nut is appropriate for industrial, commercial, and trade applications where metric fasteners and stainless steel material grades are specified. Typical use cases include HVAC equipment frames, plumbing support hardware, pool and water treatment equipment mounting, and electrical enclosure assembly. The 18-8 A2 stainless steel grade provides resistance to rust and chemical exposure in both indoor and outdoor environments. The DIN 985 standard designation makes this nut a direct specification match on fabrication drawings and engineering specs that call out that standard.

Compatibility

Designed for use with M20 x 2.50 right-hand threaded fasteners and bolts conforming to DIN or equivalent metric standards. No specific equipment model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified mechanic, technician, or tradesperson familiar with metric fastener specifications. Ensure the mating bolt or stud is free of debris, corrosion, and damage before seating the nut. Nylon insert lock nuts are generally intended for single-use applications, as the locking insert loses effectiveness after repeated cycling. Follow applicable mechanical codes and torque specifications from the equipment manufacturer or structural engineer of record.
