Washers

Flat, spring, panel (penny), copper and fibre washers in zinc, stainless steel and copper, in metric and imperial sizes.

Match the washer's inside diameter to the bolt, checking whether it is metric or imperial. Penny washers spread the load on thin panels, spring washers help resist loosening, and copper or fibre sealing washers on sump plugs and fittings are best replaced each time they are undone.
