- Partial threading configuration optimizes grip length for specific clamping requirements
Professional Applications & Engineering Value
This 3/8"-24 UNF hex head screw delivers exceptional engineering value through its steel construction and cadmium plating, specifically designed to address demanding industrial challenges. The combination of Class 3A thread fit and fine UNF threading ensures leak-proof seals and vibration resistance in high-stress applications, while the external hex drive facilitates rapid assembly in confined spaces. Particularly valuable in aerospace fastening systems and precision machinery, this partially threaded configuration allows engineers to precisely control clamping force distribution across critical joints. The 120,000 PSI tensile strength provides a significant safety margin for structural applications where failure is not an option, making it ideal for assemblies requiring both precision and durability under dynamic loading conditions.
Specification Summary & Compliance
This fastener maintains precise Class 3A thread fit tolerances per UNF standards with 3/8"-24 fine threading and right-hand thread direction. Manufactured to meet AN6-30A specifications for aerospace and industrial applications, the screw features Rockwell C26 hardness and 120,000 PSI tensile strength. The inch system measurement ensures compatibility with North American industrial standards, while the cadmium plating provides RoHS-compliant corrosion protection for extended service life in demanding environments.
