A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer).
* Easy to fix
* Abrasion resistance
* Optimum quality
The washer seems to be a thin plate with just a concentration hole which is then used to load a fine fastener equally. For increased safety, a washer may be inserted throughout the end before a wired fitting (such as a screw) is moved into a surface.
The bolt head as well as nozzle do not scratch or dent the surface of both secured pieces which ultimately can loosen the fixing. Furthermore, driving a wood screw may cause wood to crack across the surface, as well as a laundry machine significantly reduces it.
Split lock cleats are split rings in helical shape. When attached, both ends apply a spring force on the attachment to provide additional friction and motion resistance. The most popular sort of lock washer are helical spring lock washers and ideal for situations with low weights. High-column washer are a sort of washer split. Internal lock washer have made teeth bite into the head and surface of the nozzle and tissue. They work best on small electrical grounding screws or screws.
