Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these 1/2"-13 UNC hex head screws deliver exceptional performance in construction, machinery assembly, and structural frameworks. The 18-8 Stainless Steel composition provides superior corrosion resistance, making them ideal for outdoor installations or chemically aggressive environments. With partial threading and coarse UNC threads, these fasteners prevent loosening under vibration while enabling quick installation. The external hex drive accommodates high torque requirements, and the 4 1/4" length with substantial grip length ensures secure connections in thick materials. These ASTM Grade B8 certified screws solve critical challenges in load-bearing assemblies where 75,000 psi tensile strength and dimensional precision are paramount.
Specification Summary & Compliance
This 1/2"-13 UNC hex head screw features Class 2A thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and interchangeability. Manufactured from 18-8 Stainless Steel to ASTM A193 specifications with ASTM Grade B8 certification, it meets rigorous industrial requirements. The fastener complies with RoHS and REACH environmental directives and is supplied in the inch system with right-hand coarse threads for optimal performance in North American industrial applications.
