    The M10 Form B Washer is manufactured from corrosion-resistant A2 AISI 304 stainless steel to BS4320 specifications, providing a durable fastening solution for indoor and general outdoor applications.

    Featuring a polished stainless steel finish and a reduced thickness of 1.2mm, this half-thickness flat washer is ideal for applications where installation space is limited.

    Designed for use with compatible M10 threaded fasteners, it helps distribute clamping pressure across the contact surface and protect mounting materials.

    Available to order in any quantity, with no minimum order charge.

    Applications & Advice

    Typical Applications:

    • Stainless steel bolts and threaded fittings
    • Garden trellis and architectural installations
    • Mechanical fastening and assemblies
    • General outdoor fixing applications
    • General-purpose fastening systems

    Use with compatible M10 bolts, nuts and threaded fittings. The reduced thickness of this Form B washer makes it suitable for applications where a thinner washer is required. Position the washer beneath the bolt head or nut to distribute clamping pressure and help protect the mounting surface. For marine or highly corrosive environments, consider A4 AISI 316 stainless steel alternatives.
