Professional Applications & Engineering Value

This left-hand thread rounded button head screw delivers critical engineering solutions where reverse threading is essential for safety and functionality. The 18-8 stainless steel composition provides excellent corrosion resistance for harsh industrial environments, while the UNC coarse threads ensure rapid installation and reliable performance in high-vibration applications. The hex drive design offers superior torque transmission compared to Phillips or slotted drives, reducing installation time and preventing cam-out issues. These left-hand threaded fasteners are particularly valuable in rotating machinery, clamping systems, and safety-critical assemblies where standard right-hand threads would naturally loosen during operation. The fully threaded configuration maximizes engagement depth, providing consistent clamping force across the entire fastener length for enhanced joint integrity.

Specification Summary & Compliance

This fastener maintains Class 2A thread fit tolerance for reliable assembly compatibility and features UNC coarse threads (6-32 size) with left-hand direction. Manufacturing adheres to inch system standards with precise dimensional control including 0.262" head diameter and 3/8" length. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring unrestricted use in industrial markets with strict chemical substance restrictions.
