A Shakeproof washer is used as a way to lock nuts in place and withstand movement caused by the environment and vibrations. Therefore, a shakeproof washer makes the fastening more secure and reliable.
Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces.
Zinc coated and plain steel shakeproof washers are for indoor use as outside they will corrode and eventually fail. A2 (regular grade) and A4 (marine grade, withstands salt) Stainless Steel are for outdoor applications.
The locking teeth are on the inside, leaving a rounded, external edge
As the teeth overlap, when the fastener is tightened the teeth are harder to squash, so a deeper indent occurs, creating a more secure lock. These are best used when the joint is intended to be permanent.
