Value Collection HLW0X2000-050BX M20 Lock Washer Ss

Product Description

The VALUE COLLECTION HLW0X2000-050BX is an M20 metric high collar split lock washer manufactured from 18-8 austenitic stainless steel, Grade A2, with a bright uncoated finish. The high collar profile provides increased axial grip compared to standard-height lock washers, making it well suited for bolted joints subject to vibration or thermal cycling. At 4.5mm thick with a minimum inside diameter of 20.2mm and a maximum outside diameter of 30.6mm, this washer is dimensioned to DIN 127B and DIN 7980 fastener standards. It is typically installed by maintenance mechanics, millwrights, pipefitters, and other trade professionals working with M20 fastener assemblies in corrosion-exposed environments.

This washer is used in metric fastener assemblies requiring a corrosion-resistant locking element. The 18-8 Grade A2 stainless steel construction makes it appropriate for marine, food-processing, chemical, and outdoor industrial applications where carbon steel hardware is not suitable. The DIN 7980 fastener standard applies, and the washer does not meet military specifications. This SKU is sold in a minimum order quantity of 5 pieces per order.

Key Features

• High collar split lock design provides greater axial locking force than standard-height washers
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance in wet and chemical environments
• Bright uncoated finish — no coating to crack, flake, or introduce dimensional variance
• Conforms to DIN 127B and DIN 7980 metric fastener standards
• Inside diameter range of 20.2 to 21.2mm accommodates standard M20 fastener shank tolerances
• Does not meet military specifications — intended for commercial and industrial applications

Compatibility

Designed for use with M20 metric fasteners in assemblies conforming to DIN 7980 dimensional requirements. Fits standard M20 screw and bolt shank diameters within the 20.2 to 21.2mm inside diameter tolerance range.

Installation Notes

Install with the split gap positioned consistently per your assembly standard to ensure uniform locking action across all fasteners in the joint. Power down or de-energize any equipment before working on bolted assemblies near electrical components. Use calibrated torque tooling appropriate to M20 fastener specifications defined by your engineering or project standard — no torque values are specified for this washer itself. Stainless steel fastener components can be susceptible to galling during installation; use appropriate anti-seize compound if required by your assembly procedure.
