Professional Applications & Engineering Value
This Grade 5 hex head screw is engineered to address critical fastening challenges in demanding sectors like industrial machinery, automotive assembly, and construction. Its zinc-plated steel construction combats rust and wear, while the UNF fine thread and Class 2A fit minimize loosening under vibration, a common issue in dynamic environments. The external hex drive and robust head design facilitate quick, torque-efficient installation, reducing labor time. With a 120,000 psi tensile strength and full threading, it ensures uniform stress distribution, making it a reliable choice for high-stress joints where failure is not an option.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including Class 2A thread fit for consistent engagement and UNF fine thread (1/2"-20) specifications. It meets ASME B18.2.1 manufacturing guidelines and is RoHS 3 (2015/863/EU) compliant, ensuring it is free from hazardous substances. The inch system measurements and right-hand threading align with common industrial practices, providing reliable interoperability in global projects.
