The Aluminum Backing Washer 14mm from ALLSTAR PERFORMANCE is a precision fastening component designed for motorsports and high-performance automotive assembly work. This backing washer serves as a critical load-distribution element under bolt heads and fastener connections, preventing material deformation and maintaining structural integrity in engine builds, suspension modifications, and chassis work. Whether you're assembling a race engine, reinforcing mounting points, or working on custom automotive fabrication, this washer ensures even clamping force distribution across delicate or thin materials.
Machined from lightweight aluminum alloy, the 14mm backing washer offers superior corrosion resistance compared to steel alternatives while reducing overall component weight—a critical consideration in performance builds where every ounce matters. The aluminum construction provides excellent machinability and won't gall or seize on fasteners, making installation and future disassembly straightforward without risk of damage to bolt threads or mounting surfaces. The 14mm bore diameter accommodates standard metric fasteners, and the washer's flat profile ensures maximum surface contact area for optimal load distribution without introducing binding or stress concentrators.
This backing washer is ideal for mechanics and fabricators working on aluminum engine blocks, thin-wall castings, composite panels, and custom chassis modifications where standard steel washers would cause material damage or fatigue. ALLSTAR PERFORMANCE's engineering makes this component essential for any build prioritizing durability and precision fit. Its compact weight of 0.11 lbs makes it suitable for weight-sensitive applications while maintaining the rigidity and strength required in demanding motorsports environments.
