Hexagon screw full thread DIN 961 M12x1.25x60-8.8

Product detailed description

The screw with a hexagonal head and a fine metric thread according to DIN 961, ČSN 021103 and ISO 8676 is designed for applications requiring precise and strong connections. This screw has a full thread up to the head, which allows it to be used in structures where maximum use of the threaded part is required.

The diameter of the screw is M12 with a fine thread pitch of 1.25 mm, which provides higher precision and strength of the connection compared to a standard metric thread. The length of the screw is 60 mm, while the width between the surfaces of the hexagonal head is 19 mm and the width between the diagonals is 21.1 mm. The head height is 7.5 mm, which provides sufficient surface area for the application of torque during assembly.

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 strength class is suitable for medium to heavy mechanical loads. The screw is not surface treated, which means that it is suitable for applications where additional corrosion protection is not required, or where subsequent surface treatment is planned according to specific project requirements.

This screw is ideal for use in mechanical engineering and construction where high precision and joint strength are required. The fine thread provides better control over preload and reduces the risk of the joint loosening due to vibration or dynamic loads.
