WIDE Body Washer

The WIDE (wide) body washer is distinguished by its increased size: its diameter is three times the diameter of the fastening bolt or stud. It is made of plain steel with galvanic zinc plating or of austenitic chromium-nickel alloys with various additives. The product has a flat round shape with a central hole for threads from M3 to M16, outer diameter — from 10 mm to 50 mm. The enlarged body washer serves as a component of a bolt or stud connection.

Due to its size, the WIDE washer reduces stress between the connected parts and prevents deformation around the fastening joint. The increased bearing area makes the connection stronger and keeps the bearing surface intact.

The name “body” does not limit the application of the WIDE washer to repair or assembly of automotive bodies — the product is also used in other industrial sectors. When choosing, the size, material and coating type are important.
