10mm ID SS Washers 10pk .865 OD

The 10mm ID SS Washers 10pk by ARP are precision-engineered fastener components designed for high-performance engine builds, competition firearms, and tactical equipment assembly. These stainless steel washers distribute load evenly across fastened joints, preventing surface damage and loosening under vibration—critical in applications where bolt failure is not an option.

Manufactured from corrosion-resistant stainless steel, these washers feature a 10mm inner diameter with a 0.865-inch outer diameter. This design ensures optimal load distribution for applications requiring metric hardware. The 10-pack quantity ensures you have spares on hand for assembly, repair, or replacement scenarios.

Operators, gunsmiths, and equipment technicians rely on ARP fasteners because they eliminate variables in critical assemblies. Use these 10mm ID stainless steel washers alongside ARP bolts for upper and lower receiver assembly, charging handle installations, or any metric-threaded connection where load distribution matters. Their stainless construction resists rust and oxidation in harsh environments, ensuring reliability in both motorsport and tactical applications.
