Self-tapping screw for steel DIN 938 M8x55-8.8

Product detailed description

The DIN 938 steel self-tapping screw with dimensions M8x55 is designed for fixed connections in steel and blind holes. This component is made of steel with a strength class of 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. The screw is uncoated, which is important to consider when using it in an environment where it could be exposed to corrosion.

The screw has a metric thread with a diameter of M8 and a pitch of 1.25 mm. The total length of the screw is 55 mm, while the thread length is 38 mm. The thread is present at both ends of the screw; the longer thread is intended for screwing into the material, while the shorter thread with a chamfer is intended for fastening the nut. The width c is 3.2 mm, the width e is 8 mm and the width a is 1.6 mm, which are important dimensions for proper fit and functionality in the structure.

This screw is ideal for applications where it is necessary to create a strong and reliable connection in steel, especially in cases where blind holes need to be used. The use of this screw is common in mechanical engineering, construction and other industries where high strength and reliability of connections are required.
