Brass Form B Washers BS 4320B

Brass Form B washers conforming to BS 4320B are load-distribution washers designed to be used with threaded fasteners such as bolts and nuts. Manufactured from brass, they offer excellent corrosion resistance and are suitable for use in demanding environments where durability and reliability are essential.

Key Features

• Conforms to BS 4320B standard
• Manufactured from brass for superior corrosion resistance
• Distributes load across a wider surface area
• Prevents surface damage beneath fastener heads and nuts
• Suitable for use in construction, automotive and manufacturing applications
• Provides stable foundation for threaded fasteners

Typical Applications

These washers are commonly specified in construction, automotive assembly, machinery installation and structural fabrication where load-bearing capacity and surface protection are important. They help prevent fastener pull-through and surface marking, making them ideal for applications involving lighter to medium loads on softer materials or where aesthetic finish must be preserved.
