DIN 979 Socket nuts are nuts that are used on all kinds of axles and shafts that are subject to vibration and dynamic loads. Holes are drilled in these axles into which cotter pins are inserted after the nut is tightened, which in turn pass through vertical slots in the nut. This allows the nut to be securely fastened and prevents it from loosening during vibration.
Fastening group DIN 979
The DIN 979 open ended nuts are made of stainless steel and belong to the stainless steel fastener group.
Materials for the manufacture of DIN 979 nuts
DIN 979 nuts are made of stainless steel grades A2 and A4, which allows the fasteners to be used at high temperature extremes and in aggressive and humid environments.
Application range of DIN 979 nuts
The DIN 979 nut is used in mechanical engineering, instrumentation, machine tool building and construction. The DIN 979 nut is used in conjunction with a cotter pin that has a locking function. The cotter pin is inserted into a slot and a pre-prepared hole in the screw/stud on which the nut is screwed.
