Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 1/4"-20 UNC hex head screws in 316 stainless steel deliver superior performance where corrosion resistance is critical. The coarse thread design ensures rapid assembly in materials like steel and aluminum, while the external hex drive accommodates high torque applications without stripping. With a 7" length and partial threading, they provide optimal grip length for structural connections in machinery, marine equipment, and chemical processing systems, reducing the risk of loosening under stress. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes them ideal for heavy-duty fastening where reliability cannot be compromised.
Specification Summary & Compliance
This hex head screw features a 1/4"-20 UNC coarse thread with Class 2A thread fit for consistent dimensional accuracy. It meets ASME B18.2.1 manufacturing specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to industry standards for safety and environmental protection.
