Salient Features of |
|
Spring Washer : |
| |
Spring Washers have the dual function of : |
| • |
Spring take up devices to compensate for developed looseness and loss of tension between components of an assembly. It is a well known fact that the initial tension in a bolt or screw is reduced by its gradual stretch, the slight wearing-down of the contracting surface or the breakdown of rust, scale or protective paint, enamel, etc., finishes. The use of a Spring Washer under the nut or bolt head exerts an axial force during this period of initial looseness, preventing the tightening pressure diminishing below a danger level, i.e. the point at which the nut and bolt can easily rotate backwards. |
| • |
Hardened thrust bearing to facilitate assembly of bolted fastenings, by decreasing the frictional resistance between the bolted surfaces and the bearing face of bolt head or nut. |
|
Material of |
|
Spring Washer : |
Washers are hardened and tempered to 42 to 47 degrees Rockwell C Scale or as per the customer’s requirement. |
| |
|
Finish of |
