Hexagon screw with collar DIN 6921 M6x40 stainless steel A2

Product detailed description

The hexagon socket head cap screw with collar according to DIN 6921, with dimensions M6x40, is made of stainless steel grade A2-70. This screw is characterized by its hexagonal head with an integrated collar, which increases the contact area and improves the distribution of pressure when tightening. The collar has a smooth surface, which allows better contact with the material and minimizes the risk of damage to the surface of the parts being joined.

The screw has a metric thread with a diameter of M6 and a pitch of 1.00 mm. The total length of the screw is 40 mm, while the thread length is 18 mm. The width between the surfaces of the hexagon head is 10 mm and the height of the head including the collar is 6.6 mm. The diameter of the collar is 14.2 mm, which ensures sufficient stability and strength of the connection.

The A2 stainless steel material provides the screw with high corrosion resistance, which makes it suitable for use in environments with higher humidity or outdoors. The strength class A2-70 indicates that the screw has a minimum tensile strength of 700 MPa, which is sufficient for most common applications. The screw is supplied without surface treatment, which preserves the natural corrosion resistance of stainless steel.

This screw is ideal for use in engineering, construction and the assembly of various structures, where high connection strength and corrosion resistance are required. Due to its design and material properties, it is also suitable for applications where aesthetics and long-term reliability of the connection are important.
