Copper Washer Assortment for Electrical Work

This 110-piece kit supplies copper and flat washers designed for electrical connections where maximum conductivity is required. The pieces are manufactured by Swordfish Tools and meet standard thickness specifications. It is suited for technicians and hobbyists who need a ready selection of hardware for wiring and terminal tasks. Builders looking for stainless steel, nylon or oversized structural washers will not find them here.

Organised Storage in a PP Case

The washers arrive in a polypropylene storage case that includes a chart printed on the inside of the lid for quick identification. The case keeps the assortment sorted and portable around the workshop. No specialised tools are needed to access or use the contents. The only common issue is misplacing the chart if the lid becomes detached or damaged.
