Screw cylindrical head - Allen DIN 912 M8x300-8.8

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is intended for applications requiring strong screw connections with high preload. This screw has a metric thread with a diameter of M8 and a length of 300 mm. It is made of steel of strength class 8.8, which means that it has a yield strength of 640 MPa and a minimum tensile strength of 800 MPa. The screw has no surface treatment, which means that it is in its basic state without additional corrosion protection, but it can be blackened to increase resistance to oxidation.

The screw head is cylindrical in shape with an internal hexagon, which allows assembly and disassembly using an Allen key, also known as a hex key. This type of head is particularly suitable for applications where the screw needs to be recessed into the material or where space is limited for the use of traditional tools.

The screw is suitable for use in engineering, construction and other technical areas where high strength and reliability of the connection are required. It is important to ensure that it is used in an environment that does not require special surface protection, or that it is additionally treated against corrosion, if necessary.
