Value Collection 365200PS M20 Split Lock Washer 316 Ss

Product Description

The VALUE COLLECTION 365200PS is an M20 metric split lock washer manufactured from 316 austenitic stainless steel to Grade A4 specification. The washer features a bright, uncoated finish and conforms to DIN 127 fastener standards. With an inside diameter ranging from 20.2 to 21.2 millimeters and a maximum outside diameter of 33.6 millimeters, this washer is sized for use with M20 fasteners. At 4 millimeters thick, it delivers the spring tension needed to resist fastener loosening under vibration and dynamic loads. Licensed trades and maintenance professionals working with stainless hardware in corrosive or marine-adjacent environments will find the 316 alloy appropriate for applications where chloride exposure is a concern.

This split lock washer is suited for use in industrial, mechanical, and trade installations where metric fasteners are specified and corrosion resistance is required. The 316 stainless steel composition provides resistance to corrosive environments, including those with salt spray or chemical exposure. It is typically installed between a nut or bolt head and the mating surface to maintain clamp load. Applications include equipment mounting, pipe support assemblies, panel attachments, and similar structural connections in plumbing, HVAC, and general mechanical service.

Installation Notes

Installation is performed by qualified tradespeople or maintenance technicians following applicable mechanical or structural codes. Place the washer over the fastener shank with the split gap facing away from any soft or plated mating surfaces to avoid scoring. Ensure the mating surfaces are clean and free of debris before assembly. Do not mix stainless steel fasteners with carbon steel hardware in the same assembly, as galvanic corrosion can result in accelerated degradation.
