Professional Applications & Engineering Value
This Grade 5 hex head screw delivers critical performance in heavy machinery, structural steel assemblies, and precision equipment where vibration resistance and high tensile strength are paramount. The extra fine 1"-14 thread provides maximum thread engagement in thin materials and adjustment-sensitive applications, while the zinc plated steel construction offers reliable corrosion protection in industrial settings. The partially threaded design concentrates clamping force precisely where needed, making it ideal for structural connections requiring controlled load distribution. Engineered to ASME B18.2.1 standards, this external hex drive fastener ensures consistent installation torque across production lines and maintenance operations.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerances with UNS thread form specifications, this 5" length screw maintains precise dimensional accuracy throughout its service life. The fastener complies with ASME B18.2.1 mechanical standards and SAE J429 Grade 5 material requirements, ensuring consistent performance across industrial applications. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, confirming the absence of restricted substances for global manufacturing operations.
