• Precision Class 2A thread fit guarantees consistent engagement and ease of assembly, minimizing installation time.
• Partially threaded design with 3/4" thread length provides secure fastening while allowing unthreaded sections for alignment or spacing.
• 5/16"-18 UNC coarse threading offers excellent resistance to vibration loosening and quick assembly in various materials.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global supply chain requirements.
• Right-hand thread direction enables standard tool usage and straightforward installation for common applications.

Professional Applications & Engineering Value

This 5/16"-18 UNC threaded stud in 18-8 stainless steel addresses critical engineering needs for durability and precision in industrial settings. The partially threaded rod design allows the unthreaded 5 1/4" shaft to act as a guide or spacer, reducing shear stress and improving component alignment in machinery, automotive assemblies, and construction frameworks. With a 70,000 PSI tensile strength and Class 2A thread fit, it ensures secure fastening under dynamic loads, while the coarse UNC thread resists jamming and corrosion in high-moisture or chemical exposures. Ideal for industrial fasteners in manufacturing and equipment maintenance, it delivers long-term reliability without compromising on regulatory standards.

Specification Summary & Compliance

This stud adheres to Class 2A thread fit tolerances with a shaft diameter tolerance of -0.005" to 0.005" for precise dimensional accuracy. It conforms to UNC thread standards with a 5/16"-18 thread size and coarse thread spacing. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial applications.
