150pcs Metric 15 Sizes Copper Flat Washers Gaskets Assortment Set Kit With Box

Description:
The
washer is a thin disk-shaped plate with a hole in the middle that is
normally used to distribute the load of a threaded fastener, such as a
screw or nut. Other uses are as a spacer, wear pad, pre-load indicating
device, locking device, and to reduce vibration. High-quality bolted
joints require washers to prevent the loss of pre-load
after the torque is applied. Washers are also important for preventing
galvanic corrosion, particularly by insulating steel screws from
aluminum surfaces.
