Hexagon screw with collar DIN 6921 M8x70 stainless steel A2

Product detailed description

The DIN 6921 hexagon socket head cap screw with M8x70 dimensions is made of A2 stainless steel, which is known for its resistance to corrosion and chemical attack. This screw is uncoated, which means that its surface is not additionally treated, thus preserving the natural resistance of the material.

The hexagon head with a collar provides increased stability and even pressure distribution during assembly, which is advantageous in applications where a strong and reliable connection needs to be ensured. The collar also serves as an integrated washer, which increases the contact area and reduces the risk of damage to the material into which the screw is fastened.

The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm, which is a standard size for this type of fastener. The total length of the screw is 70 mm, while the thread length is 22 mm, which allows sufficient insertion into the nut or threaded hole.

The width of the hexagonal head is 13 mm, which corresponds to the standard dimensions for this type of screw and allows the use of common assembly tools. The height of the head including the collar is 8.1 mm, while the diameter of the collar is 18 mm, which ensures sufficient support and stability under load.

The strength class A2-70 indicates that the screw has a yield strength of 700 MPa, which guarantees high strength and reliability in various applications, including those subject to dynamic loads or vibrations. This screw is ideal for use in environments where high corrosion resistance is required, such as exterior structures, the chemical industry or food facilities.
