Professional Applications & Engineering Value
This 5/16"-18 UNC partially threaded stud delivers exceptional value in demanding mechanical and industrial settings. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for applications exposed to moisture, chemicals, or outdoor elements. The coarse UNC thread design ensures rapid installation and disassembly, reducing labor time in maintenance and production lines. With a 70,000 psi tensile strength and Class 2A thread fit, this stud maintains precise tolerances under vibration and dynamic loads, preventing loosening in machinery, automotive assemblies, and structural frameworks. The partial threading allows for secure positioning in blind holes or when precise unthreaded shaft engagement is required, offering engineers flexible solutions for complex fastening challenges.
Specification Summary & Compliance
This stud features a 5/16" shaft diameter with a tolerance of -0.005" to 0.005", 3/4" thread length, and total 4" length. It conforms to UNC coarse thread standards with Class 2A external thread fit for consistent performance. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and health safety standards.
