Professional Applications & Engineering Value

This 3/8"-16 brass thumb screw delivers exceptional engineering value across industrial applications where frequent access and corrosion resistance are critical. The spade head design provides substantial surface area for manual operation, eliminating tool requirements in maintenance-heavy environments like electrical enclosures, machinery guards, and production equipment. The fully threaded brass construction maintains consistent UNC coarse threading throughout the 1-1/2" length, ensuring maximum thread engagement and vibration resistance in high-cycle applications. With 50,000 psi tensile strength and Rockwell B40 hardness, this thumb screw withstands repeated tightening cycles while the brass material naturally resists corrosion in humid or chemical-exposed environments. The Class 2A thread fit guarantees precise dimensional accuracy for reliable performance in precision assemblies requiring quick-release functionality.
