Product Description

Standard:F436

Description:

      F436 washers, also known as plain washers, are specified by the ASTM F436 standard. They are used in structural applications to provide a larger bearing surface and distribute the load when used with bolts or screws. The size range you mentioned, 1/4" to 4", refers to the diameter of the bolt or screw they are designed to work with.

      When it comes to surface finishes for F436 washers, two common options are zinc plated and hot-dip galvanized (HDG). Let's explore each of these finishes:

      1.Zinc plated: Zinc plating involves applying a thin layer of zinc to the surface of the washer. This coating provides moderate corrosion resistance and acts as a protective barrier against moisture and oxidation. Zinc-plated washers are commonly used in indoor or dry environments where exposure to harsh elements is limited. They offer a silver or slightly yellowish appearance.

      2.Hot-dip galvanized (HDG): HDG involves immersing the washers in a bath of molten zinc, creating a thicker and more robust coating compared to zinc plating. Hot-dip galvanizing provides excellent corrosion resistance, making it suitable for use in outdoor or highly corrosive environments. HDG washers have a distinctive dull gray or matte finish.

      The choice between zinc plated and HDG finishes depends on the specific application requirements, considering factors such as the operating environment and the desired level of corrosion protection. HDG is typically preferred for applications where enhanced corrosion resistance is vital, such as in outdoor structural projects or environments with exposure to moisture, chemicals, or salt. Zinc plated washers may be suitable for less demanding environments, such as indoor applications or those with minimal exposure to corrosive elements.
