The S/S Flat Washers - 7/16 ID x 13/16 OD (10) by ARP are essential components for tactical builds, firearms assembly, and field-grade equipment maintenance. These stainless steel washers are designed to distribute load evenly across bolt connections, which helps prevent surface damage and loosening due to vibration, a common failure point in high-recoil environments.
Manufactured from durable stainless steel, the 7/16-inch inner diameter accommodates standard fasteners, while the 13/16-inch outer diameter enhances load distribution across a wider surface area compared to smaller washers. This stainless construction also offers excellent resistance to corrosion and oxidation, making these washers suitable for use in wet environments and for extended outdoor storage.
Professional armorers, tactical builders, and military personnel depend on high-quality washers to secure critical connections on rifles, carbines, and accessory rails. The ten-pack quantity provides an economical option for inventory stocking or completing multiple builds, ensuring that users have the necessary components for reliable performance in the field.
