Brass Washers
Brass Washers are essential mechanical components used in fastening assemblies to evenly distribute load beneath a bolt, screw, or nut head. By spreading pressure across a wider surface area, brass flat washers reduce stress concentration, helping to prevent damage to both the fastener and the mating surface.
For assemblies requiring a complete fastening solution, Brass Washers are commonly paired with Brass Screws, Brass Nuts and Brass Bolts to ensure material compatibility and consistent corrosion resistance.
Brass Washers to DIN 125 & BS 4320
Most Brass Washers are manufactured to recognised industry standards such as DIN 125 and BS 4320, ensuring full compatibility across different fastener manufacturers. These standards typically specify an outer diameter approximately twice the inner diameter, providing optimal load distribution and secure fastening performance.
Choosing standardised DIN 125 Washers or BS 4320 Washers guarantees dimensional accuracy, interchangeability and reliable performance in professional and industrial applications.
If your project requires alternative materials, you may also consider Stainless Steel Washers for enhanced corrosion resistance or Nylon Washers for lightweight and insulating properties.
When would Brass Washers be used?
Electrical Applications: Brass offers significantly better electrical conductivity than steel, making Brass Washers ideal for electrical connections, grounding points, and electronic assemblies. For insulated installations, consider combining with Nylon Spacers or Plastic Fasteners.
Non-Sparking Environments: Unlike steel, brass does not produce sparks when struck or abraded. This makes Brass Washers suitable for hazardous environments such as oil & gas facilities, mining operations, and industrial processing plants.
Decorative & Architectural Uses: With their attractive gold-like finish, Brass Washers are frequently used alongside Brass Fasteners in furniture manufacturing, musical instrument production, and architectural fittings where both appearance and performance are important.

Frequently Asked Questions
Brass washers are used to spread load and provide corrosion resistance in plumbing, electrical and decorative applications.
No, a brass washer does not have to be used with a brass screw. It can be paired with steel or stainless steel screws, but material compatibility should be considered in corrosive environments to reduce galvanic corrosion.
No, brass does not rust. Rust is specific to iron and steel. Brass can tarnish or develop a patina over time, especially in outdoor or damp environments, but it does not form rust.
DIN 125A is a German standard specifying a washer with an outside diameter roughly twice the inside diameter. BS 4320 is the British equivalent and comes in multiple forms — Form A (narrow), Form B (standard) and Form C (wide) — offering a wider outer diameter for greater load distribution. Both are widely used across UK industry!
Yes. Brass is a non-ferrous alloy and is non-magnetic, making brass washers suitable for use in sensitive electrical and electronic assemblies where magnetic interference must be avoided!
No. Unlike steel, brass does not produce sparks when struck or abraded. This makes brass washers a mandatory specification in explosive atmosphere environments such as oil and gas installations and mining equipment.
