Triangular Nut with Collar

The DIN 22425 triangular nut with collar is designed for mounting and installing explosion-proof mining electrical equipment and is used in electrical instrument engineering. Its main application is the installation of electrical equipment in mines.

It is made from property class 5.8-8.8 steel, electro-galvanized or electro-nickel-plated steel, L63 brass, various non-ferrous metals, and A1-A2 grade stainless steel. Non-magnetic, moisture-resistant and heat-resistant metals capable of withstanding increased operating loads are most commonly used. Coated steel nuts do not have non-magnetic properties.

Property class of the part: 5-8. Product height – 1d-1.2d. Internal thread diameter – M8-M10. This fastener has no equivalents: if a GOST standard recommends using the DIN 22426 nut, that specific nut must be installed.

Secure fastening of the nut requires a hole of the appropriate size in the part being fastened. The hole diameter should slightly exceed the diameter of the fastener’s collar, and its depth should fully match the height of the nut. Fastening is carried out using a special tool.
