Screw cylindrical head - hex DIN 912 M12x75-12.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for fixed screw connections that require high preload. This screw is ideal for applications where high strength and reliability of connections are required. Its metric thread with a diameter of M12 and a pitch of 1.75 mm allows for precise and secure connection of components.

The screw has a cylinder head with internal hexagon, which allows assembly using an Allen key, thus ensuring efficient torque transmission and minimizing the risk of head damage during assembly. The head diameter is 18 mm, the head height is 12 mm and the width of the internal hexagon is 10 mm, which provides sufficient surface area for applying torque.

The screw material is 12.9 strength class steel, which means that the screw has high tensile strength and is able to withstand high loads. The surface treatment is untreated or blackened, which provides basic protection against corrosion, however, additional surface treatment is recommended for applications in aggressive environments.

The total length of the screw is 75 mm, while the thread length is 36 mm, which allows sufficient insertion into the nut or threaded hole to ensure a solid connection. The screw is suitable for use in mechanical engineering, the automotive industry and other areas where high-strength fasteners are required.
