Parallel Face Washers
Detroit Diesel

These washers with parallel faces are precision-machined to ensure even load distribution and optimal sealing in heavy-duty applications. With a 21 mm diameter, they are ideal for use under bolts and fasteners where maintaining clamping force is crucial. Their flat, parallel surfaces prevent uneven stress and deformation, which could compromise joint integrity. Made from durable materials, these washers resist deformation and corrosion, making them suitable for high-stress environments such as engine assembly and transmission mounting. Proper use of these washers enhances the reliability of fastened connections, preventing loosening and leaks. They are essential in maintaining the structural integrity of critical engine components. Source One Parts Center recommends these washers for their quality and precision, vital in ensuring the durability of heavy-duty systems.
