Professional Applications & Engineering Value
This black-oxide steel thumb screw delivers exceptional engineering value for industrial applications requiring frequent adjustments or tool-free maintenance. The knurled head provides superior manual grip, eliminating slippage during high-torque operations in machinery, electrical enclosures, and assembly jigs. Its 70,000 psi tensile strength and Rockwell B84 hardness ensure reliable performance in vibration-prone environments, while the coarse UNC 3/8"-16 threading enables rapid installation and removal. The fully threaded 2" length offers versatile positioning capabilities, making it ideal for securing panels, fixtures, and access points where durability and ease of use are critical.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit standards with UNC 3/8"-16 coarse threading and right-hand direction. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The black-oxide surface treatment enhances corrosion resistance while maintaining dimensional stability across the 2" fully threaded length.
