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 hardened steel 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.






Features:



This set of flat washers are made of copper of good electrical conductivity and thermal conductivity.



Flat washers can spread a load, and prevent damage to the surface being fixed, and insulate steel screws from surface.

Flat washer is applied when the hole is a larger diameter than the fixing nut. There are many different sizes of washers in this set from which you can use for different purposes.
