Stainless Steel A2 Flat Washers and Spring Washers are essential hardware components used in various applications to distribute loads, prevent the loosening of fasteners, and provide a level of cushioning or spring-like action. Let's explore the features and applications of both types of washers:
Stainless Steel A2 Flat Washer:
Material: A2 stainless steel, also known as 304 stainless steel, is the primary material used for A2 flat washers. It offers good corrosion resistance and is suitable for most non-corrosive environments.
Shape: Flat washers are typically thin, circular discs with a central hole. They have a flat surface on both sides.
Function: Flat washers serve several purposes, including distributing the load of a fastener (e.g., bolt or screw) over a larger area, protecting the underlying surface from damage, and reducing friction between the fastener and the surface.

Stainless Steel A2 Spring Washer (Split Washer):
Material: A2 stainless steel is also used for A2 spring washers. However, the material's properties are adapted to suit the spring washer's function.
Shape: Spring washers are typically conical or wavy-shaped, with one or more splits or gaps along the circumference.
Function: Spring washers are designed to create tension or preload in a fastener assembly. When compressed, they exert a spring-like force, helping to prevent fasteners from loosening due to vibrations and thermal expansion/contraction.
It's important to choose the appropriate type of washer (flat or spring) based on the specific requirements of your application. Flat washers are primarily used for load distribution and surface protection, while spring washers are used to provide tension and prevent the loosening of fasteners. Additionally, the choice of stainless steel A2 ensures corrosion resistance in most non-corrosive environments.
