Square Heavy Washers

Square Heavy ZP Spring Washers are heavy-duty locking washers designed to help maintain bolt tension and reduce loosening caused by vibration and movement. Finished with zinc plating for added corrosion resistance, they are ideal for industrial, engineering, construction, and general fastening applications.

Square Heavy Black Spring Washers are heavy-duty locking washers designed to provide strong tension and vibration resistance in bolted assemblies. Their black finish and square-section design make them suitable for industrial, engineering, machinery, and structural fastening applications where extra grip and load support are required.
