Professional Applications & Engineering Value

This partially threaded stud with cotter pin delivers critical engineering solutions where vibration resistance and secure retention are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery, marine, and automotive applications exposed to moisture and chemicals. With its Class 2A thread fit and UNF fine threading, the stud maintains clamping force in high-vibration environments where standard fasteners would loosen. The integrated hairpin cotter pin offers positive mechanical locking, eliminating the need for additional lock washers or thread-locking compounds. This combination of precision shaft diameter control and 2-inch thread length ensures optimal stress distribution across connected components, making it ideal for pivot points, linkage assemblies, and adjustable mechanisms requiring both strength and reliability.

Specification Summary & Compliance

Manufactured to exacting standards with Class 2A thread fit per UNF specifications, this stud features a 3/8"-24 fine thread with right-hand direction and 2" thread length. The shaft maintains a diameter tolerance of -0.005" to 0.005" for precision assembly. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use worldwide.
