Countersunk Allen screw DIN 7991 M6x30-8.8

Product detailed description

The countersunk screw with internal hexagon according to DIN 7991, ISO 10642 and ČSN 021144, with dimensions M6x30, is designed for applications requiring precise fit and high preload. The screw has a metric thread with a partial thread length of 24 mm and a pitch of 1.00 mm. The total length of the screw is 30 mm, while the thread diameter is M6.

The screw head is countersunk, which allows it to be embedded in the material without protruding, and has an internal hexagon with a dimension of 4 mm, which facilitates the transmission of torque using an Allen key. The head height is 2.5 mm and the head diameter is 12 mm, while the countersunk head angle is 90°, which ensures a stable and firm connection.

The screw is made of steel of strength class 8.8, which means that it has a minimum yield strength of 640 MPa and a minimum tensile strength of 800 MPa. This material is suitable for applications where high strength and resistance to mechanical stress are required. The surface of the screw is without special treatment, which is suitable for applications where there are no special requirements for corrosion resistance.

This screw is ideal for use in mechanical engineering, construction and assembly, where it is necessary to achieve a strong and aesthetically clean connection without the head protruding above the surface of the material.
