• Regulatory compliance with ASME B18.2.1, RoHS 3, and REACH for quality assurance

Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw delivers critical performance in heavy machinery, structural assemblies, and marine equipment where corrosion resistance and high tensile strength are paramount. The 18-8 stainless steel material prevents rust in humid or chemical-exposed settings, while the coarse UNC threading and Class 2A fit reduce cross-threading risks during high-speed installations. With an external hex drive and generous head dimensions, it allows for high-torque application without stripping, making it a reliable choice for construction, transportation, and industrial maintenance projects that require durable, fully threaded fasteners.

Specification Summary & Compliance

This hex head screw features a 1/2"-13 UNC coarse thread with Class 2A thread fit per ASME B18.2.1 specifications, ensuring dimensional accuracy and interchangeability. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for regulated industries and environmentally conscious procurement.
