Overview
DIN 6799 is a dimensional standard for retaining washers used in industrial, mechanical, and motion control applications. It defines washer geometry, groove compatibility, tolerances, and installation characteristics to support reliable shaft retention and assembly performance. The standard is commonly referenced together with material, hardness, and inspection standards depending on the application requirements. DIN 6799 retaining washers are commonly manufactured from spring steel, stainless steel, and corrosion-resistant material options. When sourcing DIN 6799 retaining washers, the standard alone may not fully define the product requirements. Additional specifications may include shaft diameter, material requirements, surface finish, corrosion protection, and certification requirements.
