Screw cylindrical head - hex DIN 912 M4x20-10.9

Product detailed description

The cylinder head screw with internal hexagon according to DIN 912, ISO 4762 and ČSN 021143 is designed for applications requiring solid screw connections with high preload. This screw has a metric thread with the designation M4 and a length of 20 mm, with a thread pitch of 0.70 mm. The cylinder head has a diameter of 7 mm and a height of 4 mm, while the internal hexagon allows assembly using an Allen key, which guarantees reliable and precise tightening.

The screw is made of steel with a strength class of 10.9, which means that it has high tensile strength and is suitable for demanding applications where high mechanical resistance is required. The surface treatment is not applied, which can be an advantage in situations where it is necessary to preserve the natural properties of the steel or where additional surface treatment is planned according to specific project requirements.

This screw is ideal for use in mechanical engineering, the automotive industry and other industries where reliable and durable fasteners are required. Its design allows for easy and efficient assembly, while the internal hexagon minimizes the risk of head damage during installation.
