Malleable Washers
A malleable washer is a cast iron washer used as a broad bearing plate under nuts and heads, often in pipe and timber connections. Its cast shape spreads load over a wide surface.
Used in pipe supports, timber connections and utility hardware where a thick bearing plate is needed. Bought by plumbing and utility suppliers.
