Washers Back-up Alum 3/16in (100pk)

Washers Back-up Alum 3/16in in a 100-pack is an essential fastener solution for tactical equipment assembly, maintenance, and field repairs. Ideal for armorers, gunsmiths, and operators, these aluminum backup washers help distribute load evenly across threaded fasteners, preventing surface damage and loosening under recoil or impact.

Constructed from aluminum, these washers offer corrosion resistance and lightweight performance, which are critical in tactical environments. They resist oxidation better than steel alternatives and do not create galvanic corrosion when paired with stainless steel fasteners, making them suitable for precision rifle builds and modern sporting rifle platforms.

Law enforcement armorers, military personnel, and civilian shooters building or maintaining AR-pattern rifles, precision bolt guns, and tactical shotguns will benefit from having this 100-pack in their maintenance kit. The bulk quantity ensures you have enough washers for multiple projects without the need for repeated ordering.
