Screw with semi-round head hex ISO 7380 M4x20 steel 10.9 without PU

Product detailed description

The ISO 7380 hexagon socket pan head screw is designed for applications where aesthetic finish and reliable fastening are required. This screw has a metric M4 thread with a length of 20 mm and a thread pitch of 0.70 mm, which ensures a precise and strong connection. The 7.6 mm diameter and 2.2 mm high pan head provides sufficient surface area for pressure distribution, minimizing the risk of damage to the material into which the screw is fastened.

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 mechanical applications. Steel of this class is able to withstand high loads without deformation, which is ideal for structures where high reliability is required. The surface treatment is not applied, which can be an advantage in cases where subsequent surface treatment is required or where the surface treatment could interfere with the function of the screw.

The 2.5 mm internal hexagon allows for efficient torque transmission during assembly and disassembly, reducing the risk of damage to the screw head. This type of groove is popular for its ability to transmit high torques and for its compactness, which allows for use in limited spaces. The screw is ideal for use in mechanical engineering, the automotive industry and other areas where high strength and reliability of joints are required.
