Why Use Metal Spring Washers?

1. washers, shaped like a round ring of a class of fasteners, used for bolts, screws or nuts of the support surface and connecting parts surface, reduce the contact surface area of the connected parts, reduce the unit area pressure and protect the connected part surface is not damaged;

2. spring washers are mainly used for anti-loose, flat washers do not relax function, that is, flat pads are only to increase the contact area, spring washers can be anti-loose, such as motor and seat-connected bolts generally to add spring washers, because the motor vibration, if there is no spring washer, the nut will be loose. Generally with vibration on the equipment on the fasteners equipped with spring washers, flanges generally do not need to level washers. Flanges without spring washers and pipe circulation of the medium has a relationship, if easy to generate pulses, it is best to add spring washers, as well as high-speed fluid, the caliber changes frequently, do not generalize.

Inner hexagonal bolt assembly. This bolt is a common piece of furniture fastening hardware. And is more important fasteners, usually used in such as the legs of the table fixed, strict metal connection is usually used with the crossbar nut, is to use spring gaskets; In practical use, due to the characteristics of the thread, the nut is easily rotated in the direction of the screw after tightening, resulting in the nut loosening; Spring washers due to the pretension, after the nut compression spring washer, under the action of pretension, the nut's triangle buckle and the bolt triangle of the screw side, tightly attached together, under the influence of friction, the nut will no longer appear loose, and the ordinary washer (also known as a round gasket or flat gas or ordinary gasket), is a spring washer under the pretension of the spring pad, increase the spring gas ket under the cushion.
