Professional Applications & Engineering Value

This brass thumb screw delivers exceptional value in applications requiring frequent adjustments or tool-less operation. The knurled head provides positive grip even with gloves or oily hands, while the low-profile round head design minimizes protrusion in compact assemblies. The 6-32 UNC coarse thread enables quick installation and superior resistance to vibration loosening in electronic enclosures, instrumentation panels, and access covers. Brass construction offers natural corrosion resistance for harsh environments and excellent electrical conductivity for grounding applications. With fully threaded design and Class 2A thread fit, these screws ensure consistent performance across production runs, reducing assembly time and maintenance requirements in industrial settings.

Specification Summary & Compliance

This thumb screw features precision 6-32 UNC coarse threading with Class 2A thread fit for consistent dimensional accuracy. The 0.138" thread diameter and 3/8" length provide standardized fastening dimensions. Manufacturing complies with RoHS 3 (2015/863/EU) regulations with exemption 6(c) for lead in copper alloy, ensuring environmental compliance for industrial applications. The combination of 50,000 PSI tensile strength and Rockwell B78 hardness guarantees mechanical reliability across repeated use cycles.
