Washers

A.R. Thomson Group supplies a full range of washers to complement our stud and nut offerings, ensuring proper load distribution, joint integrity, and reliable performance in critical bolting applications.

Our washer solutions are available in a variety of materials and configurations to meet industry standards and project specific requirements.

Available Washer Types

ASTM F436 Hardened Steel Flat Washers

Manufactured to meet ASTM F436 requirements, these hardened washers are designed for use with high strength bolting assemblies. They provide consistent load distribution and help prevent embedding and deformation in structural and heavy duty applications.

Stainless Steel Washers

Stainless steel washers offer excellent corrosion resistance and are well suited for use in harsh and corrosive environments. Available in a range of grades, they are ideal for applications where durability and long term performance are critical.

Belleville Washers

Belleville washers, or disc spring washers, are designed to provide preload, compensate for thermal expansion, and maintain bolt tension under dynamic conditions. Commonly used in applications subject to vibration, thermal cycling, or load variation.

Why Specify Quality Washers

Improved load distribution and joint stability
Reduced risk of bolt loosening and failure
Protection of mating surfaces
