Hex Flange Bolt
The hex head bolt with washer is a standard mechanical fastener designed to distribute pressure evenly and prevent loosening of the connection. Diameter ranges from M6 to M36, with lengths from 20 to 200 mm. Made from carbon steel, alloy steel, or stainless steel A2/A4, tensile strength ranges from 500–900 MPa. The accompanying metal or stainless washer enhances shear and tensile load capacity while protecting the structure surface.
Threads are manufactured according to ISO or DIN standards, allowing rapid installation with wrenches or power tools. Galvanized, chrome, or epoxy coating improves corrosion resistance under harsh environments. Common applications include metal structures, industrial machinery, bridges, construction equipment, and light profiles. Optimized mechanical design with washer increases connection durability and reduces maintenance requirements.
