Value Collection 836200PS M20 Split Lock Washer 18-8 Ss

Product Description

The VALUE COLLECTION 836200PS is an M20 metric split lock washer manufactured from 18-8 austenitic stainless steel, Grade A2, conforming to DIN 127 fastener standard. Split lock washers are installed beneath a nut or bolt head to resist loosening caused by vibration and torque relaxation. The helical split creates a spring-like load that maintains clamping force across the joint. At 4mm thick with a minimum inside diameter of 20.2mm and a maximum outside diameter of 33.6mm, this washer is sized for M20 fastener assemblies. The 18-8 Grade A2 stainless construction provides corrosion resistance suitable for wet, outdoor, and chemically mild environments.

This washer is used in mechanical assemblies, structural connections, and equipment installations where M20 fasteners are specified and vibration resistance is required. Common applications include HVAC equipment mounting, pump and motor base fastening, pipe support brackets, electrical enclosure hardware, and general industrial or commercial construction. The metric sizing and DIN 127 compliance make it appropriate for equipment of European origin or any assembly calling out metric fastener standards. Minimum order quantity is 10 pieces.

Key Features

• 18-8 austenitic stainless steel, Grade A2 — corrosion resistant for wet and outdoor use
• DIN 127 fastener standard compliance for metric assemblies
• Helical split design resists loosening under vibration and dynamic loads
• Inside diameter range of 20.2 to 21.2mm fits M20 fasteners
• 4mm thickness provides substantial spring load and clamping retention
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed for use with M20 metric fasteners in assemblies conforming to DIN 127 or equivalent metric split lock washer specifications.

Installation Notes

Split lock washers are installed between the bearing surface of the nut or bolt head and the joint material, with the split gap positioned to bite into both surfaces as the fastener is tightened. Power down or de-energize any equipment before accessing fastener assemblies on live systems. Use appropriate metric hand tools and follow torque requirements specified by the equipment manufacturer or applicable mechanical codes. Do not reuse deformed or fully compressed lock washers, as they will not provide reliable spring load after permanent set.
