Military Standards Flat Washer

Military Standards Flat Washers - 800 Series

Stainless Steel Flat Washers fitting Military Specifications

MS - Military Standards. The overriding characteristics of MS fasteners compared to commercial products is the extensive inspection and lot tractability for MS, guaranteeing the chemical, physical and dimensional qualities. While commercial fasteners may look similar and happen to pass many tests given MS products, the commercial fasteners lack the pedigree of guaranteed quality for chemical, physical and dimensional aspects that users who order MS fasteners rely on.

Military Standard Flat Washers, also known as 800 series washers, are available in corrosion resistant 18-8 Stainless Steel for a long lasting assembly.
