Screw cylindrical head - hex DIN 912 M20x110-8.8 galvanized

Product detailed description

The cylinder head screw with internal hexagon, also known as an Allen screw, is manufactured according to DIN 912, ISO 4762 and ČSN 021143. This screw has a metric thread with a diameter of M20 and a length of 110 mm. Its head has a cylindrical shape with a diameter of 30 mm and a height of 20 mm, while the internal hexagon allows the use of an Allen key for assembly. The screw is made of steel with a strength class of 8.8, which means that it has a yield strength of 640 MPa and a tensile strength of 800 MPa, which makes it suitable for use in applications requiring high preload.

The screw thread is metric, with a pitch of 2.50 mm, and the thread length is 52 mm. The surface treatment is white zinc-plated, which provides protection against corrosion and increases the durability of the screw in environments with higher humidity or in outdoor applications. This screw is ideal for solid screw connections in engineering, construction and other industries where a reliable and durable connecting component is needed.
