Washer SELMUL10
Mack

Washer SELMUL10 is a precision washer designed to distribute load and minimize surface damage on fastener assemblies. The correct washer reduces friction, protects softer materials, and helps maintain clamping force across a range of operating temperatures. This variant typically sits between a nut or bolt head and a mating surface, improving load transfer and reducing the risk of galling or indentation. When selecting washers, consider inner diameter, outer diameter, thickness, and material (steel, stainless, or composite) to match the fastener grade and the application’s environmental exposure. In high‑duty trucks, washers contribute to long‑term joint integrity, particularly in suspension links, mounting brackets, and engine supports where repeated cycles can otherwise loosen connections. Regular inspection ensures washers remain intact and properly seated, supporting predictable service life. Source One Parts Center.
