N12 Tanged Lock Washer (W-12)

The N12 Tanged Lock Washer (W-12) by Mittler Bros is a precision fastening component designed for critical military and tactical applications where vibration resistance and load security are non-negotiable. Built to mil-spec standards, this tanged lock washer prevents fastener loosening under the extreme conditions encountered in field operations, vehicle systems, and equipment assembly. Whether you're outfitting tactical platforms, maintaining armored vehicles, or assembling precision gear systems, this washer ensures your hardware stays secure through repeated deployment cycles and harsh environmental exposure.

The tanged design features a single bent tang that locks firmly against the fastener and underlying surface, mechanically preventing rotation and loosening that standard washers cannot resist. Unlike spring lock washers that degrade under compression, the tanged lock washer maintains its locking force indefinitely, making it ideal for high-reliability applications in weapons systems, vehicle assemblies, and equipment where re-torquing is impractical. The N12 specification ensures compatibility with standard 1/2-inch fasteners, delivering consistent performance across platforms used by law enforcement and military units where equipment failure creates operational risk.

Tactical professionals and maintenance specialists rely on the N12 Tanged Lock Washer for assembly of modular systems, weapon platforms, and vehicle components where fastener integrity directly impacts safety and performance. Installation is straightforward—place the washer under the bolt head with the tang inserted into a hole or slot in the underlying component, then torque to specification. This washer integrates seamlessly into mil-spec maintenance kits and is essential inventory for armorer operations, field repair teams, and anyone responsible for maintaining equipment that cannot tolerate hardware failure.
