Screw M4x20x20 DIN 912 strength class 8.8 zinc (pack 6pcs) evropodves STROYMETIZ 3100141

DIN 912 internal hex screw is a fastener used to create threaded connections and can be installed in high-load assemblies. It is made of high-quality materials and is characterized by a long service life. Advantages of DIN 912 hex screws: Potentially higher torque and clamping force, which can be achieved with a socket head screw compared to a screwdriver-type screw fastener, making them a preferred option in many assembly productions. The internal hex is more resistant to stripping and wear than cross-recess slots, and the deep, tight fit of the tool allows for easy application of the required tightening torque without slipping. Another advantage of cylindrical head bolts is the possibility of installation in deep blind holes of mechanisms and in confined spaces where access to hex bolts is difficult.
