DIN 127-B is a standard spring washer (grommet) used to prevent self loosening of fasteners. DIN 127-B is a washer that consists of a ring that is divided and bent at the required angle to the main plane of the fastener. Such washers are placed under the heads of screws and bolts, nuts, and also put on studs to prevent the threaded part from loosening and to increase the clamping property. The difference between a B-shaped washer and an A-shaped washer is that its ends are straight, with a lower spring effect, but uniform contact with the surface.
Application: equipment manufacturing, mechanical engineering and in parts used in the interaction of external dynamic loads.
Material: stainless steel. A4 steel grade allows the bolts to be used at high temperature extremes and in aggressive and humid environments.
