Professional Applications & Engineering Value
This 1/4-20 UNC partially threaded stud is engineered from 18-8 Stainless Steel to address critical challenges in industrial settings, such as corrosion in humid or chemical-exposed environments. The Class 2A thread fit and coarse UNC threading enable reliable, repeatable fastening in machinery, automotive assemblies, and structural frameworks, minimizing the risk of cross-threading and ensuring consistent torque performance. With a 70,000 PSI tensile strength, it withstands dynamic loads and vibrations, making it suitable for high-stress applications like pump systems, conveyor brackets, and equipment mounting. The partially threaded design allows for precise clamping force distribution, reducing stress concentration and enhancing joint durability in precision shaft and alignment-critical installations.
Specification Summary & Compliance
This stud adheres to UNC coarse thread standards with a Class 2A external thread fit, ensuring dimensional accuracy per industry norms. Shaft diameter tolerance is maintained within -0.005" to 0.005" for precise fitment. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global markets and environmentally conscious operations.
