Professional Applications & Engineering Value
Engineered for precision and durability, this 1/4"-20 UNC partially threaded stud solves common industrial fastening challenges. The 18-8 Stainless Steel material provides excellent corrosion resistance in manufacturing, marine, and chemical processing environments where moisture and chemicals degrade ordinary fasteners. The Class 2A thread fit ensures smooth assembly while maintaining secure connections in vibration-prone equipment. With 70,000 PSI tensile strength, it withstands heavy mechanical loads in machinery frames, electrical enclosures, and structural assemblies. The coarse UNC threading enables quick installation in maintenance operations and resists jamming in dirty conditions. This stud delivers reliable performance where partial threading is required to maintain alignment while providing threaded engagement at one end.
Specification Summary & Compliance
This stud maintains Class 2A thread fit per UNC standards with ±0.005" shaft diameter tolerance for precision assembly. Manufactured to UNC coarse thread specifications with right-hand threading on one end. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The inch system measurement and standardized threading provide interchangeability with existing industrial components.
