Screw with half-round head hex ISO 7380 M3x12 steel 10.9 zinc

Product detailed description

The ISO 7380 hex socket head cap screw is designed for applications where reliable strength and corrosion resistance are required. This particular model has a metric M3 thread with a length of 12 mm, with a thread pitch of 0.50 mm. The screw is made of 10.9 strength steel, which means it has a high tensile strength of at least 1040 MPa, and is suitable for use in more demanding mechanical applications.

The screw head has a hemispherical shape with a diameter dk of 5.7 mm and a height k of 1.65 mm, which allows for aesthetic embedding in the material without significant protrusion. The s 2 mm internal hexagon allows for efficient torque transmission when assembling and disassembling using an Allen key, minimizing the risk of head damage.

The surface treatment of the screw is white zinc plating, which increases its resistance to corrosion and ensures a longer service life even in environments with higher humidity or in contact with chemicals. This treatment also contributes to a better appearance and protection against mechanical wear.

The screw is ideal for use in mechanical engineering, the automotive industry and other technical areas where high joint strength and resistance to external influences are required. It is suitable for applications where it is necessary to ensure a strong and reliable connection of components with the possibility of repeated assembly and disassembly.
