Value Collection LW7XX00400-100BX M4 Split Lock Washer 316 Ss

Product Description

The VALUE COLLECTION LW7XX00400-100BX is an M4 metric split lock washer manufactured from 316 austenitic stainless steel to Grade A4 specification. The washer features an inside diameter of 4.1 to 4.4 millimeters and a maximum outside diameter of 7.6 millimeters, with a thickness of 0.9 millimeters. The bright, uncoated finish leaves the material surface exposed for maximum corrosion resistance inherent to 316 alloy. This washer conforms to DIN 127B and is sold in a minimum order quantity of 100 pieces. It is suited for trade and maintenance professionals who need reliable metric fastener hardware for corrosive or marine-adjacent environments.

This split lock washer is intended for use with M4 metric fasteners in applications where vibration resistance and corrosion resistance are required. The 316 stainless steel alloy makes it appropriate for marine, chemical processing, food service, and outdoor installations where exposure to moisture or corrosive agents is a concern. Maintenance technicians, mechanical contractors, and industrial service professionals commonly use this washer when assembling or servicing equipment requiring metric hardware to DIN standards.
