Carbon Steel Hexagon Socket Head Cap Bolts
Product introduct
Carbon steel hexagon socket cap screws are made of high – quality medium carbon steel. Through heat treatment processes such as quenching and tempering, they have high strength and good toughness, capable of withstanding large tensile forces and impacts. They are suitable for fields with high – strength requirements, such as machinery manufacturing, automobile assembly, and construction engineering.
The unique cap head design, with a cylindrical concave hexagonal hole, increases the contact area with the wrench, enabling high – torque tightening for a more secure connection. It also effectively prevents head wear and slippage. The hexagon socket structure is convenient for operation in narrow spaces. With a special wrench, installation and disassembly are quick and easy. After precision machining and surface treatments such as galvanizing and blackening, the anti – corrosion ability of the bolts is improved, and their appearance is more beautiful.
The product’s thread sizes range from M3 to M36, and the lengths are from 10mm to 300mm, meeting different installation needs. They are produced and tested strictly in accordance with national standards such as GB/T 70.1 and German standards like DIN 912, ensuring that the product’s dimensional accuracy and mechanical properties meet high – standard requirements and the quality is reliable. We offer professional selection advice and comprehensive after – sales services, providing efficient and durable fastening solutions for various projects.
