12mm Washers 10pk .995 OD Non-Chamfer

The ARP 12mm Washers 10pk .995 OD Non-Chamfer represents a critical fastener solution for precision firearm assembly, upper receiver builds, and tactical equipment maintenance. These washers distribute load evenly across bolt heads and threaded surfaces, preventing sink-in and protecting finished surfaces during installation. Whether you're building a competition rifle, maintaining duty weapons, or assembling tactical gear, quality washers ensure proper torque retention and long-term reliability under recoil and vibration stress.

Engineered with a .995 inch outer diameter and non-chamfered design, these 12mm washers provide a larger contact surface area that's essential when working with high-strength fasteners in critical applications. The non-chamfered construction eliminates sharp edges, reducing the risk of damage to surrounding components and anodizing during installation. ARP's precision manufacturing ensures dimensional consistency across all ten pieces, eliminating the frustration of mismatched or oversized washers that can compromise fit and function in tight receiver tolerances.

Armourers, gunsmiths, and tactical shooters benefit most from stocking these washers for upper receiver builds, scope rail installation, and accessory mounting. They work seamlessly with ARP fastening systems and are compatible with standard 12mm bolt applications across AR platforms, precision rifles, and general-purpose firearms. The ten-pack quantity accommodates multiple builds or provides backup inventory for professional workshops, ensuring you never halt a project due to missing fasteners.
