The Purpose of spring Washers and Why They’re Used With Fasteners

What is Spring washer?

Typically consisting of a flattened, circular- or disc-shaped piece of metal with a hole in the middle, washers are often used in conjunction with threaded fasteners. Before a threaded fastener like a screw is driven into a surface, a washer may be placed through the end. The actual spring washer, however, isn’t driven into the surface, leaving many people to wonder what purpose they serve.

The spring washer is a mechanical machine component useful in combination with a screw fastener. More specifically, the product works well along with a bolt and nut. Washers typically consist of a flattened, circular, or disc-shaped piece of metal. The portion has a hole in the middle. Before attaching threaded fasteners into a surface, it is essential to place a washer through the end. These products usually keep the screw from loosening or distributing the load from the other components such as nut or bolt head over the surface area. For load distribution, thin flat rings of soft steel work well. Also, different types of washers prevent loosening. Here, various types of washers act as springs to counterbalance increased distance between the head of a bolt and the nut. Also, it balances distance between the head of a screw and the object holding clamp.

Addition to the spring action, these washers have a point, that strike into the workpiece and the screw head. The attachment provides a firm locking. The washer’s points are known as tooth or shake-proof lock washers. The teeth present on washer are capable of bending and twisting across the plane of the washer face. The conical washer has spring movement, but they can perform locking action due to friction. Another type of washer, i.e., the helical spring washer is one of the most commonly applicable lock washers.
