Value Collection A98013 Wedge Lock Washer M6 316L Ss

Product Description

The VALUE COLLECTION A98013 is a metric wedge lock washer designed to prevent fastener loosening under vibration and dynamic loading. Built from 316L stainless steel in an uncoated finish, this washer delivers strong corrosion resistance in wet, chemical, or marine service environments. It fits M6 threaded fasteners with an outside diameter of 0.4331 inches, a minimum OD of 0.4244 inches, and an inside diameter range of 0.2559 to 0.2598 inches. The wedge lock design uses mating cam faces that increase clamping force when the joint attempts to rotate loose, making it a reliable choice for critical bolted connections in trade and industrial applications.

This washer is suited for use in HVAC equipment assemblies, electrical panel mounting, plumbing fixture brackets, and any bolted joint that experiences vibration, thermal cycling, or mechanical shock. The M6 metric thread size is common in both residential and light commercial mechanical equipment. The 316L material grade makes it appropriate for outdoor installations, coastal environments, pool mechanical rooms, and other corrosive service conditions where standard carbon steel or 304 stainless would be marginal.

Key Features

• Wedge lock cam geometry resists fastener back-out under vibration without thread damage
• 316L stainless steel construction provides superior resistance to chlorides, acids, and moisture
• M6 metric thread fitment covers a wide range of mechanical equipment bolted joints
• Uncoated finish eliminates coating delamination concerns in high-moisture environments
• Compact profile: 0.4331 inches OD allows use in tight flange and bracket clearances
• Sold in quantities of 25 per package, minimum order of 1 package

Compatibility

Designed for use with M6 metric threaded fasteners as an anti-loosening washer in bolted assemblies requiring vibration resistance and corrosion-resistant hardware.

Installation Notes

Installation is performed by mechanics, HVAC technicians, electricians, or plumbers during equipment assembly or service. Always de-energize and isolate equipment before replacing hardware in live assemblies. Wedge lock washers must be installed as a mated pair with cam faces together and serrated faces against the mating surfaces to function correctly. Follow equipment manufacturer torque specifications for the M6 fastener being used.
