The M6 ID .890 OD Chamfer SS Washer 1pk is a precision fastening component designed for high-performance engine builds, suspension modifications, and critical mechanical assemblies where load distribution and vibration resistance are non-negotiable. Whether you're working on a stroker engine, turbo manifold installation, or custom suspension setup, these stainless steel washers provide the structural integrity needed to prevent bolt loosening and distribute clamping force evenly across soft materials or precision surfaces.
Manufactured from 300-series stainless steel, this washer features a precisely machined .890-inch outer diameter with an M6 (6mm) inner diameter bore and a chamfered edge design that reduces stress concentration at bolt contact points. The chamfer geometry prevents sharp edges from digging into surrounding materials, a critical advantage when fastening lightweight aluminum heads, carbon-fiber components, or thin-wall castings common in modern engine modifications. The 1-pack quantity makes these ideal for individual replacement, prototype testing, or as spares in your shop inventory.
Technicians and engine builders choose this M6 ID .890 OD Chamfer SS Washer for applications where OEM hardware alone doesn't provide adequate clamping surface area or corrosion resistance. Common uses include custom intake manifold bolting, fuel rail fastening on turbocharged builds, and accessory bracket installation on aluminum engine blocks where vibration and thermal cycling demand superior fastener security. Stainless construction resists rust and corrosion in underhood environments, ensuring long-term reliability regardless of climate or fuel system exposure.
