• Fine UNF threading offers improved vibration resistance and finer adjustment control compared to coarse threads.
• Partial threading design allows for secure fastening on one end while leaving a smooth shank for alignment or component mounting.
• Environmental compliance with RoHS 3 and REACH standards, ensuring safe use in regulated industries and global markets.
• Right-hand thread direction ensures compatibility with standard assembly tools and procedures, streamlining installation.

Professional Applications & Engineering Value

This 5/16"-24 UNF partially threaded stud is engineered to address common industrial challenges such as component misalignment, vibration-induced loosening, and corrosion in demanding settings. The 18-8 Stainless Steel material provides excellent resistance to rust and chemical exposure, making it suitable for machinery, automotive assemblies, and outdoor equipment. The fine UNF threading and Class 2A thread fit deliver tight tolerances that prevent backlash and ensure consistent clamping force, reducing maintenance needs. Its partial threading allows one end to be securely fastened while the unthreaded section supports precise positioning, ideal for use in pumps, motors, and structural frameworks where reliability and durability are critical.

Specification Summary & Compliance

This stud adheres to UNF fine thread standards with a Class 2A thread fit for external threads, ensuring dimensional accuracy per industry norms. Shaft diameter tolerance is maintained within -0.005" to 0.005", and it is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally responsible sourcing and usage in global markets.
