This A2 stainless steel penny washer is suitable for use with M5 bolts and screws, offering a wider surface to spread the clamping force. The 25mm outer diameter helps protect softer materials, such as timber, plasterboard or thin sheet, from damage during installation.
On site, it is commonly applied when fixing components to substrates with large or elongated holes, preventing pull-through and maintaining secure assemblies. The washer can be used either singly or in a stack, providing versatility for different load or spacing requirements in general construction and repair works.
