Value Collection A98015 Wedge Lock Washer 5/16 316L Ss

Product Description

The VALUE COLLECTION A98015 is a wedge lock washer designed to maintain clamp load and resist vibrational loosening in bolted assemblies. Manufactured from 316L stainless steel in an uncoated finish, this washer is suited for applications where corrosion resistance is a priority. It fits a 5/16 inch thread with an outside diameter of 0.534 inches and an inside diameter ranging from 0.336 to 0.344 inches. The minimum outside diameter is 0.526 inches. Maintenance technicians, millwrights, and industrial service professionals install these washers where fastener security is critical under cyclic load or vibration.

This wedge lock washer is appropriate for use in industrial, marine, chemical processing, and general mechanical assemblies where stainless steel hardware is required. The 316L material grade offers enhanced resistance to chloride environments and pitting compared to standard 304 stainless. It conforms to ISO 14001 and ISO 9001 standards, making it suitable for quality-controlled manufacturing and maintenance environments. Sold in a package quantity of 10.
