150 Pieces Copper Flat Washers, 15 Metric Sizes Assortment Set with Box

Each washer is a thin disk with a centre hole, used to spread the load of a threaded fastener such as a screw or nut. They can also serve as spacers, wear pads, locking devices and vibration reducers, and help insulate steel screws from a surface. The copper material offers good electrical and thermal conductivity. Sizes range from M5 to M22 with varying inner diameter, outer diameter and thickness.
