8.8 Grade Din 127 Stainless Steel Spring Washer White Zinc Hot Plating

DIN127 spring washer

Description

The spring washer is installed under the nut to prevent the nut from loosening.

It is stated in national standards.

Hexagon slotted nut is specially used with the bolt with hole at the end of the screw to insert the cotter pin from the groove of the nut into the hole of the screw to prevent the nut from loosening automatically. It is mainly used in occasions with vibration load or alternating load.

Methods to prevent automatic loosening of nuts (or bolts) in mechanical design and manufacturing include:

1. Add spring washer; (easy to do)

2. Use hexagon slotted nut + cotter pin; (processing procedures increased year on year)

3. Pad the lock washer; (processing procedures increased year on year)

4. Insert the steel wire into the hexagon head opening of the hexagon bolt

Spring washers are used to prevent looseness. For example, the bolts connecting the motor and the base generally need to add spring pads, because if the motor vibrates, the nuts will loosen. Generally, the fasteners on the equipment with vibration are equipped with spring gaskets, and the flanges generally do not need to add gaskets! Whether to add spring gaskets to the flange is related to the medium flowing in the pipeline. If it is easy to produce pulses, it is best to add spring gaskets. There is also high-speed fluid, and the caliber changes frequently Don't generalize On some valves, the gland flange of the stuffing box needs spring gaskets The automatic selection of spring gasket is included.
