Back Up Washers 3/16 Large O.D. 100pk Steel

The Back Up Washers 3/16 Large O.D. 100pk Steel by ALLSTAR PERFORMANCE are essential fastener components for serious engine builders, transmission specialists, and chassis fabricators. These washers are designed to prevent fastener pull-through on soft materials and distribute load across wider surface areas, making them ideal for various automotive applications.

Featuring a 3/16-inch center hole and a large outside diameter profile, these steel washers are engineered to resist deformation under high clamping pressure and vibration cycling. The oversized O.D. increases the bearing surface area compared to standard washers, preventing bolt heads and fastener hardware from sinking into softer materials like aluminum and plastic.

Professional mechanics and fabricators rely on ALLSTAR PERFORMANCE backup washers for fastening critical components to soft or low-strength substrates. The 100-pack format is perfect for shops handling multiple builds, ensuring that technicians have consistent and reliable hardware throughout their projects.
