The DIN 935 (GOST 5918) crown nut is a unique element used in critical devices such as the production of railroad cars for freight and passenger transportation, aircraft construction, and agricultural machinery. It can be used together with a cotter pin (DIN 94) to attach to screws, bolts and studs of the appropriate size (for detailed advice, please call +380442400024).
To fix the DIN 935 crown nut, a hole with a diameter of the size of the split cotter pin is drilled in the workpiece, then the hardware is screwed onto the workpiece with the rod and fixed in a position where the ends of the hole completely coincide with the slots on the end. After that, a cotter pin is placed through the hole and slots on the threaded rod, the ends of which are spread to the polar sides, and pressed hard against the upper part of the crown.
Materials for use in DIN 935: steel 6,8,10 (galvanized, hot zinc), stainless steel – A2-70; A2-80; A4-70; A4-80.
