Hexagon screw with collar DIN 6921 M12x70 stainless steel A2

Product detailed description

The DIN 6921 hexagon socket head cap screw, with dimensions M12x70, is made of A2 grade stainless steel. This screw is characterized by its hexagonal head with a smooth collar, which ensures better pressure distribution on the material surface and reduces the risk of damage during assembly.

The screw diameter is M12, which corresponds to an outer thread diameter of 12 mm. The screw length is 70 mm, while the thread length is 30 mm. The screw has a metric thread with a pitch of 1.75 mm. The width between the faces of the hexagon head is 16 mm and the height of the head including the collar is 11.5 mm. The collar diameter is 26.6 mm, which provides additional stability and strength of the connection.

The A2 stainless steel material is known for its corrosion resistance, which makes this screw suitable for use in environments with higher humidity or outdoors. The strength class A2-70 indicates that the bolt has a minimum yield strength of 700 MPa, which makes it suitable for use in applications where high strength and reliability are required.

This bolt is supplied without surface treatment, which is common for stainless steel materials, as their natural resistance to corrosion eliminates the need for additional protective layers. The bolt is suitable for a wide range of applications in engineering, construction and other industries where high joint strength and resistance to corrosive influences are required.
