1/8in Back Up Washers 500Pk Aluminum

The ALLSTAR PERFORMANCE 1/8in Back Up Washers 500 Pack in aluminum delivers a cost-effective fastener solution for high-volume assembly and repair work. With 500 pieces per pack, these standard backup washers provide the quantity needed for production runs, race shop operations, or maintenance programs where consistent fastener performance matters.

Each washer measures 0.125 inches inner diameter, 0.375 inches outer diameter, and 0.06 inches thick—dimensions engineered to distribute clamping force evenly across bolt and threaded stud joints. Aluminum construction provides a lightweight alternative to steel while resisting corrosion in workshop and outdoor environments. The natural finish requires no additional surface treatment, simplifying inventory management. These washers work across automotive assembly, aerospace applications, and general industrial fastening where load distribution and thread protection are priorities.

Bulk packing in sets of 500 reduces per-unit cost compared to smaller quantities, making this ideal for shops, manufacturers, and technicians who maintain standing inventory. ALLSTAR PERFORMANCE's positioning in motorsports and performance fastening means this product meets the practical standards of serious builders and repair professionals. The standardized dimensions ensure compatibility across common fastening applications without requiring size verification for each installation.

Whether stocking a shop, assembling custom builds, or managing maintenance programs, aluminum backup washers at this quantity and price point eliminate the need for repeated small orders. The 500-count format balances practical shelf space with sufficient supply for extended production cycles or ongoing fastening needs.
