Crown nuts

Crown nuts - fasteners consisting of a hexagonal base with a thread and a cylindrical strip in the form of a crown (with slots). The design features of crown nuts allow them to be used in structures that are affected by vibration and deformation forces. Crown nut is especially widely used in the automotive industry and in the manufacture of furniture.

Varieties and characteristics of crown nuts

There are two main types of nuts:
• slotted nuts - slots made in the nut itself;
• crown nuts - a cylindrical section is pre-drilled in a high nut, and through slots are already drilled in it.

It should be noted that there are several standards governing the production and operation of crown nuts. The main ones are:

 • DIN 935 - the standard regulating production of a crown nut in classical execution, with a standard and small step of a carving, with a metric and inch carving;
• DIN 937 - standard governing the production of low crown nuts.

The crown nut is made of high-strength carbon and stainless steel (8, 10), made of brass and covered with galvanized method. Nuts made of various metals are widely represented on the Ukrainian hardware market. In particular, in our online store you can pick up and buy a crown nut of any type.

The method of fastening the crown nut
If you have already decided on the type and size of the hardware you need and decided to buy a nut, you need to know about the nuances of its further attachment and use.
In order to securely fasten the crown nut, it is necessary to screw it all the way to the thread of the paired part so that the slots on the crown of the crown nut coincide with the hole in the threaded part of the bolt rod, axis or threaded stud. Through the combined slots and hole you need to insert a cotter pin of the desired size and unbend its ends in opposite directions (in the regulations for each size of the crown nut indicate the exact size of the cotter pins - length and diameter).
If possible, the cotter pin is placed with the ring up. This will help to avoid the loss of the cotter pin in case of breakage of its ends (it can break in case of strong bending of its ends).
