Professional Applications & Engineering Value

This 1/4"-20 UNC threaded stud delivers exceptional engineering value through its 18-8 stainless steel composition and double-ended design. The corrosion-resistant properties make it ideal for applications exposed to moisture, chemicals, or outdoor elements, preventing rust-induced failure in wood screw assemblies and industrial equipment. With threaded sections on both ends (3" and 1-1/2"), it solves connection spacing challenges while maintaining structural integrity. The Class 1A thread fit and coarse UNC threading ensure quick, reliable installation in wood, plastic, and metal components, reducing assembly time and minimizing thread damage risk. This double-ended rod serves as an efficient threaded connector in machinery, furniture manufacturing, and construction projects where durable, corrosion-resistant fastening solutions are critical.

Specification Summary & Compliance

This threaded stud maintains precision with Class 1A thread fit on external threads and adheres to UNC coarse thread standards (1/4"-20). The 4-1/2" overall length features 3" and 1-1/2" threaded sections on opposite ends with right-hand threading. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications while delivering reliable performance in demanding fastening scenarios.
