Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade 5 zinc-plated steel hex head screw addresses critical challenges in machinery assembly, structural frameworks, and equipment manufacturing. The UNC coarse thread and external hex drive enable rapid installation even in confined spaces, while the serrated locking flange prevents spontaneous loosening under dynamic loads. With a tensile strength of 110,000 psi and uniform zinc-plated coating, it resists shear forces and environmental corrosion, reducing downtime and replacement costs. Ideal for construction, automotive, and metalworking sectors requiring inch-measurement fasteners that meet rigorous performance and regulatory demands.
Specification Summary & Compliance
This fastener adheres to Class 2A thread fit and UNC coarse thread standards for precise dimensional accuracy. It conforms to SAE J429 (IFI 111) specifications for Grade 5 mechanical properties and is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and material traceability. The fully threaded design and 2 1/2" length provide consistent clamping force across applications.
