Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 1/2"-13 UNC hex head screws in 400 Nickel material address critical challenges like corrosion, high stress, and regulatory compliance. The coarse thread design ensures rapid installation and secure holding power in soft or brittle materials, while the partially threaded shank minimizes stress concentration and thread damage. With an external hex drive, they facilitate high-torque fastening in confined spaces, making them ideal for heavy machinery, marine equipment, and chemical processing systems where corrosion-resistant fasteners are essential. Their robust construction and adherence to ASTM F468 and military specifications provide long-term reliability, reducing maintenance costs and downtime in critical assemblies.
Specification Summary & Compliance
This hex head screw features a 1/2"-13 UNC thread with Class 2A fit for precise dimensional accuracy, a length of 2 1/2", and partial threading. It meets ASTM F468 and MIL-S-1222 specifications for material and performance, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial use.
