Stainless steel Allen bolts are made from corrosion-resistant alloys such as A2 equivalent to 304 and A4 equivalent to 316, with tensile strengths ranging from 500 to 700 MPa. These bolts are typically manufactured in diameters from 3 to 24 millimeters and lengths from 6 to 200 millimeters. The head design features an internal hexagon with a 90-degree angle, produced according to DIN 912 or ISO 4762 standards. A2 grade is suitable for general environments, while A4 is ideal for acidic and marine conditions. The surface is available in brushed or polished finishes to enhance corrosion and rust resistance.
The threads of stainless steel Allen bolts are usually designed according to ISO standards, available in both coarse and fine pitches, and machined with ±0.1 millimeter tolerances. These bolts come in both full-thread and half-thread versions and maintain stable mechanical properties at temperatures up to 400 degrees Celsius. Surface hardness ranges from 200 to 400 Vickers and is controlled through annealing or cold working. Their use is common in food, chemical, pharmaceutical, and medical equipment industries due to their hygienic and corrosion-resistant properties.
