Half-round head screw with hex collar ISO 7380FL M4x25 steel 10.9 without PU

Product detailed description

The hex socket head cap screw with collar according to ISO 7380FL is designed for applications requiring an aesthetic and solid connection. This particular model has a metric M4 thread with a length of 25 mm and a pitch of 0.70 mm. The head of the screw is hemispherical with a collar, which increases the contact area and improves the pressure distribution during assembly. The head diameter is 9.4 mm, the head height is 2.2 mm and the width of the hex socket is 2.5 mm, which allows the use of a standard Allen key for assembly.

The screw is made of steel grade 10.9, which means that it has a high tensile strength, namely a minimum of 1040 MPa, and is suitable for applications where increased mechanical resistance is required. The screw is not surface-treated, which can be an advantage in environments where additional corrosion protection is not required or where direct electrical conductivity is required.

This screw is ideal for use in mechanical engineering, construction and other technical areas where reliable and precise connection of components is required. The internal hexagon allows for easy and safe assembly even in confined spaces.
