Product Description

Standard:USS

Description:

      USS washers, also known as plain washers, are commonly used in the United States and are specified by the Unified Screw Thread Standard (USS). They are used to distribute the load and provide a larger bearing surface when used with bolts or screws. The size range you mentioned, 1/4" to 3", refers to the nominal diameter of the bolt or screw they are designed to work with.

      When it comes to surface finishes for USS washers, two common options are plain and Dacromet. Let's explore each of these finishes:

      1.Plain finish: Plain washers have no additional surface treatment or coating applied to them. They are made of raw metal without any specific protective or decorative coating. Plain washers are commonly used in applications where a specific surface finish is not required, or where other measures, such as lubrication or environmental protection, are used to maintain the desired performance and corrosion resistance.

      2.Dacromet: Dacromet is a coating that provides excellent corrosion resistance. It is a non-electrolytic, water-based coating that contains metal particles and inorganic compounds. Dacromet coatings offer high levels of corrosion resistance, including resistance against salt spray, chemicals, and extreme temperatures. They are commonly used in applications where superior corrosion protection is required, such as in marine, automotive, and industrial environments.

      The choice between plain and Dacromet finishes for USS washers depends on the specific application requirements and the desired level of corrosion resistance. Plain washers may be suitable for applications where corrosion resistance is not a primary concern, while Dacromet-coated washers are preferred for environments where enhanced corrosion protection is necessary.
