Types of washers

To spread load, start with a Flat Washer, or a Mudguard / Penny Washer when the material is thin or soft and a standard washer would pull through. A Square Washer gives a large bearing face on timber and channel. To stop a joint working loose, choose a Spring Washer, Tooth Lock Washer or Safety / Vibration-Lock Washer; a Disc Spring (Belleville) Washer holds high spring force in a small space.

For bolted steel, the Structural Washer page covers hardened AS/NZS 1252 washers, and Load-Indicator (DTI) Washers show when the specified bolt tension is reached. The Taper, Sampson & Specialty Washer page has 8° taper washers for tapered flanges. Sealing Washer keeps water out around roofing and cladding fixings, and Cup / Finishing Washer tidies a countersunk screw head.
