7/16 ID Washer .950 OD Non-Chamfered (20pk)

The ARP 7/16 ID Washer .950 OD Non-Chamfered (20-pack) is a precision fastener component designed for high-strength bolt assembly applications where load distribution and proper clamping force are critical. These black oxide flat washers feature a 7/16-inch inner diameter and .950-inch outer diameter, providing the increased surface area needed to protect underlying materials from bolt head or nut pressure during assembly and tightening cycles.

ARP manufactures these washers in hardened steel with black oxide finish, which offers corrosion resistance superior to bare steel while maintaining the dimensional consistency required in precision engine building and structural fastening. The non-chamfered edge design ensures full bearing surface contact without edge distortion. At 0.4 lbs for the complete 20-piece set, these washers are lightweight components that add minimal mass while providing essential load-spreading functionality. Each washer in this set meets ARP's manufacturing tolerances for repeatability across multiple fastening applications.

Users in automotive engine assembly, machinery repair, and structural construction rely on washers of this specification to prevent fastener embedment, distribute clamping loads evenly, and maintain consistent bolt preload over repeated assembly and disassembly cycles. The .950-inch outer diameter provides substantial bearing surface suitable for applications involving aluminum or composite materials that require wider load distribution. Black oxide finish resists light corrosion in shop and garage environments, making these washers suitable for both initial assembly and long-term service applications. The 20-pack quantity reduces the need for frequent reordering while maintaining inventory for multiple projects.
