DIN436 Square Washer
DIN436 square washer is a heavy-duty fastening component designed to provide increased load distribution and improved support in structural and mechanical assemblies. The DIN436 square washer features a square outer shape with a large bearing surface, helping spread clamping force over a wider area and reducing stress on connected materials.
Manufactured from carbon steel, stainless steel, or customized materials, the DIN436 square washer offers excellent mechanical strength, dimensional stability, and reliable performance in demanding applications. It is widely used in timber construction, steel structures, machinery frames, electrical installations, and industrial fastening systems.
Product Overview
The DIN436 square washer is engineered for applications where standard round washers cannot provide sufficient support. Its square shape offers a larger contact area and better resistance against rotation when installed on structural components.
Compared with conventional flat washers, the DIN436 square washer provides improved load distribution and helps prevent surface deformation, especially when used with wood, steel plates, or large structural components.
This washer is commonly installed with bolts and screws in heavy-duty fastening systems and is widely selected by OEM manufacturers, construction companies, machinery builders, and engineering contractors.
