Standard Allen screw DIN912

The DIN 912 Allen bolt is one of the most widely used types of machine screws, featuring a cylindrical head and internal hex socket. These bolts are typically manufactured in diameters ranging from M1.6 to M64 and are available in strength grades 8.8, 10.9, or 12.9. The thread angle is 60 degrees, and the pitch can be either coarse or fine depending on the bolt size. The head diameter is generally 1.5 times the nominal thread diameter, and the head height is approximately equal to the thread diameter. For example, an M6 bolt has a head diameter of 10 millimeters and a height of 6 millimeters. Thread tolerance is defined as class 6g, ensuring precise manufacturing standards.

DIN 912 bolts are designed to transmit high torque using an Allen key while occupying minimal installation space. These bolts are commonly made of carbon or alloy steel with heat treatment and surface coatings such as phosphate, zinc plating, or black oxide to enhance corrosion resistance. The recommended tightening torque for an M10 bolt in grade 12.9 is approximately 100 newton meters. These bolts are widely used in machinery, robotics, industrial equipment, and precision mechanical assemblies. The accuracy of the internal socket ensures a secure and durable connection under both static and dynamic loads.
