Black Washers - 10mm ID x 3/4 OD (10)

Black Washers - 10mm ID x 3/4 OD are precision fastener components essential for tactical equipment assembly, firearm builds, and military hardware applications. These washers distribute load across bolt and screw connections, preventing fastener heads from sinking into softer materials and reducing stress concentration. Whether you're assembling rifle furniture, mounting optics, securing rail systems, or building custom tactical gear, properly sized washers ensure long-term durability and reliability under field conditions where vibration and repeated use demand solid mechanical integrity.

These ARP washers feature a 10mm inner diameter (ID) and 3/4-inch outer diameter (OD), engineered for use with M8 or similar metric fasteners in standard tactical applications. The black finish provides corrosion resistance and eliminates light reflection—critical for maintaining equipment visibility control in operational settings. Manufactured to consistent tolerances, each washer in this 10-pack delivers reliable load distribution and vibration dampening, ensuring fastened components remain secure through repeated movements, recoil impulses, and environmental exposure without loosening or shifting.

Law enforcement armorer, military gunsmiths, and tactical equipment builders depend on quality washers to maintain structural integrity of modular systems and custom assemblies. These washers work seamlessly with standard metric bolts used in rail mounting, stock attachment, handguard assembly, and optics platform installation. A 10-pack provides redundancy for multiple projects or team builds, making this set an economical addition to any tactical maintenance kit or equipment assembly bench.
