Aluminium Sealing Washers

Aluminium sealing washers sit under a nut or bolt head to give a smooth seating face and spread the load across a wider area. They're a common choice for oil drain plugs and for outdoor fittings exposed to harsh weather. Aluminium is non-magnetic, conducts current and does not spark easily, so these washers also suit electrical work.

Available in a wide range of sizes, listed as inside diameter x outside diameter x thickness. Smaller sizes come in packs of 100, mid sizes in packs of 50 and the largest in packs of 25.
