Low crown nut DIN 937 M42x1.50

Product detailed description

The low crown nut according to DIN 937, ISO 7035 and ČSN 021412 is a specific type of fastener designed to secure threaded connections using a cotter pin. This component is designed for applications where space is limited and reliable joint security is required.

The nut has a hexagonal shape with a low profile, which allows it to be used in places with limited height. It is equipped with a fine metric thread with dimensions M42x1.50, which means that the outer diameter of the thread is 42 mm and the thread pitch is 1.50 mm. This type of thread is suitable for applications where higher accuracy and fine adjustment are required.

The dimensions of the nut are as follows: diameter d1 is 58 mm, height m is 22 mm, width s (between surfaces) is 65 mm and width e (between diagonals) is 71.3 mm. The crown height, designated as k, is 14 mm. The slot n for the cotter pin is 9 mm, which allows for secure fastening and prevents the nut from loosening spontaneously.

The nut is made of steel with a strength class of 17H, which guarantees high mechanical resistance and reliability in demanding conditions. The surface treatment is not applied, which means that the nut is without surface treatment and should therefore be used in an environment where it is not exposed to corrosive influences or should be additionally treated with a suitable surface treatment according to the requirements of the application.

This nut is ideal for use in mechanical engineering, the automotive industry and other areas where it is necessary to ensure a firm and reliable connection of threaded components with the possibility of repeated loosening and fastening without loss of functionality.
