Plain Washers

A plain washer, also known as a flat washer, is a fundamental yet essential component placed under a nut or bolt head. Its primary functions are to evenly distribute clamping force over a wider area, protect sensitive surfaces from damage during tightening, and in some cases, provide a smoother bearing surface to improve torque accuracy.

Product details

Typical Applications:

General Assembly & Machinery: Used in virtually all industries as a standard part of a bolted joint to prevent local yielding and damage to the connected material.
Piping & Flange Connections: Serves as a standard element in gasket and flange assemblies to ensure even pressure distribution on the sealing surface.
Automotive & Electronics: Protects painted, plated, or soft substrate surfaces from being scarred by rotating fastener heads or nuts during installation.

Our Product & Custom Capabilities:
We supply plain washers in a complete range of standard sizes and specifications (e.g., ASME B18.22.1, DIN 125). Our customization focuses on precise engineering to meet specific application needs:

Material & Grade: Low-carbon steel, hardened spring steel (e.g., for ASTM F436M washers), stainless steel, aluminum, and non-metallic options.
Dimensional Precision: Controlled inner/outer diameters and thickness to exact tolerances, ensuring proper fit and consistent load distribution.
Surface Finish: A variety of platings and coatings, such as zinc, nickel, or phosphate, to prevent corrosion and suit different environmental conditions.

Our plain washers provide a reliable and cost-effective foundation for secure fastening, ensuring the long-term integrity and performance of your assembled products.
