Flat set screw - hex DIN 913 M4x16 galvanized

Product detailed description

The flat set screw with internal hexagon is manufactured according to DIN 913, which also corresponds to ISO 4026 and ČSN 021187. This screw is designed to lock parts without damaging the seating surface, which is achieved by its flat end. The internal hexagon, also known as an inbus, allows for efficient torque transmission during assembly and disassembly using a hexagonal wrench.

The screw has a metric thread with a diameter of M4 and a pitch of 0.70 mm. The total length of the screw is 16 mm, while the head diameter is 2.5 mm and the B1 width is 2 mm. The screw material is steel of strength class 45H, which guarantees high resistance to mechanical stress and long service life. The surface treatment is performed by galvanizing with white zinc, which provides protection against corrosion and increases the aesthetic appearance of the component.

This screw is part of the set screw group and is suitable for applications where a firm and precise adjustment of the position of parts is required without the risk of surface damage. It is mainly used in mechanical engineering, in the assembly of mechanical assemblies and in situations where precise regulation and fixation of components is required.
