Allen steel bolts are made from carbon steel in various grades such as 5.6, 8.8, and 10.9, offering tensile strength between 400 and 1040 MPa. These bolts are manufactured in diameters ranging from 3 to 30 millimeters and lengths between 8 and 250 millimeters. The standard head angle is typically 90 or 120 degrees, designed according to DIN 912, ISO 4762, and ANSI B18.3 standards. The internal hexagonal geometry of Allen bolts allows for high torque transmission. Surface hardening heat treatments increase wear resistance and mechanical durability. Coatings such as cold galvanizing, hot-dip galvanizing, or black phosphate provide corrosion protection. These bolts are fastened with Allen keys and are widely used in high-precision connections in metal industries, machinery manufacturing, and structural applications.
Allen steel bolts feature metric threads based on ISO standards and are produced in both coarse and fine thread types with manufacturing tolerances of ±0.2 millimeters. Thread profiles often conform to DIN 13 standards and are available in partial or full thread versions. Strength classes 8.8 and 10.9 are suitable for applications with high mechanical loads and repeated stress. These bolts exhibit high resistance to torsional torque and maintain their position without deformation. Mechanical properties are verified through tensile tests, hardness measurements, and metallographic analysis. Allen steel bolts offer a cost-effective solution with adequate strength for construction, automotive, industrial equipment, and engineered fastening systems.
