The stainless steel Allen bolt is one of the most widely used industrial fasteners, typically manufactured from A2 equivalent to 304 or A4 equivalent to 316 alloys. These bolts offer tensile strength ranging from 500 to 800 MPa and maintain stable performance against corrosion, rust, and temperature fluctuations up to 400 degrees Celsius. The bolt head angle is usually 90 or 120 degrees and comes in flat, button, or cylindrical head types. Bolt diameters typically range from 3 to 24 millimeters, with lengths varying from 6 to 200 millimeters. Manufacturing standards include DIN 912, ISO 4762, and ANSI B18.3, which define the mechanical and geometric specifications. These bolts are generally fastened using Allen keys that match the bolt diameter.
The surface finish of stainless steel Allen bolts can be polished, matte, or brushed, achieved through processes such as electrolytic treatment or shot peening. The strength classes are commonly offered in grades 50, 70, or 80, indicating yield and ultimate tensile strength. The thread pitch usually follows ISO standards and is available in both coarse and fine threads with high machining precision. These bolts are used in marine environments, food, pharmaceutical, and chemical industries due to their antioxidant and hygienic properties. Depending on the application, the threading may be full or partial, with a manufacturing tolerance of ±0.1 millimeters. Stainless steel Allen bolts are an ideal choice for applications requiring precision, durability, and chemical resistance.
