Black Washer 5/8 ID x 1.30 OD 1pk

The Black Washer 5/8 ID x 1.30 OD 1pk is a precision flat washer designed for fastener applications that require reliable load distribution and vibration resistance. This component is essential for various mechanical assemblies, including automotive, firearms, industrial, and tactical equipment builds.

By distributing fastener load over a larger surface area, the washer prevents bolt heads and nuts from sinking into softer materials while maintaining consistent clamping force under operational stress. The washer features a 5/8-inch inner diameter (ID) and a 1.30-inch outer diameter (OD), providing optimal surface contact for medium-duty fastening applications. Its black oxide finish offers corrosion resistance and a professional appearance.

Builders, gunsmiths, and equipment technicians rely on this washer for critical fastening applications where joint integrity and longevity are paramount. It integrates seamlessly into bolt-together assemblies, chassis work, rail systems, and component mounting, ensuring effective load distribution and vibration damping.
