Value Collection A98019 Wedge Lock Washer M12 316L Ss

Product Description

The VALUE COLLECTION A98019 is a wedge lock washer designed for M12 metric threaded fastener assemblies. The wedge lock design uses opposing cam faces to resist loosening under vibration and dynamic loads, making it a reliable choice for industrial and mechanical fastening applications. Constructed from 316L stainless steel in an uncoated finish, this washer offers strong corrosion resistance in wet, chemical, or marine environments. The outside diameter measures 0.7756 inches with a maximum inside diameter of 0.5197 inches and a minimum inside diameter of 0.5039 inches. Licensed tradespeople and maintenance mechanics typically install this washer as part of a bolted joint assembly where vibration-resistant fastening is required.

This wedge lock washer is suited for use in corrosive or high-vibration environments where standard flat or split-ring washers may not maintain clamp load over time. Typical applications include industrial equipment, marine hardware, chemical processing assemblies, and mechanical systems subject to cyclic loading. The 316L stainless steel grade makes it appropriate for outdoor, saltwater-adjacent, or chemically aggressive service conditions. This washer is sold in a package quantity of 10 units.

Installation Notes

Wedge lock washers are installed in mated pairs with the serrated faces outward against the bearing surface and the cam faces facing each other. Ensure mating surfaces are clean and free of debris before assembly. Follow applicable torque guidelines for the specific fastener grade and joint design per relevant standards. Do not mix wedge lock washer pairs from different lots or sizes, as mismatched cam profiles reduce effectiveness.
