What is a spring washer?

Question

could be in engineering?

Answer 1

If it is the type of washer that goes with nuts and bolts? This washer is bent so that it compresses like a spring as the nut tightens on it. The spring tension makes it hold firmer and means that a fixing is less likely to loosen due to vibration.

Answer 2

A spring washer is a specific type of lock washer, so called because it serves to lock a hardware stackup against being unscrewed or pulled out. It is compressed as the bolt is tightened, and it exerts a force that opposes unscrewing. This makes it unlikely for the bolt to become unscrewed due to the loading of the finished assembly. A spring washer usually has a slight conical shape. Another type of lock washer is called a split washer. It acts as a spring as well, and in a more literal sense (because it's like one coil of a spring), but it is not usually referred to as a spring washer.

Answer 3

As far as I know, and Im no expert, its a normal looking washer with a split in it which has then been twisted lightly. When a bolt or srew is put up against it, unlike a normal washer, the twist acts as a spring and helps stop the bolt etc coming loose.

Answer 4

Its a washer that is thicker than the plain washer, it is scarf-cut and has a slight helix thus provide tension when the bolt is torqued up. Basically you have to imagine it's a bit like a single coil of a close wound spring.

Answer 5

It is a washer that assists nuts and bolts to stay tight under conditions that could loosen them such as vibration. Some are shaped like a flat ring but open at one side and pulled out of alignment. Another is a closed flat ring with a jagged inner ring edge that grips when the nut is tightened. These are called shake proof. Yes it is engineering
