• Excellent corrosion resistance due to high-quality brass construction, ensuring longevity in various environments
• Reliable thread engagement with fully threaded UNC coarse pattern and Class 2A fit for quick, secure fastening
• Optimized low-profile head (3/8" diameter, 3/16" height) for space-constrained applications while maintaining easy access
• High mechanical durability with 50,000 psi tensile strength and Rockwell B78 hardness for repeated use without stripping
• Broad regulatory compliance meeting RoHS 3 standards for safe use in industrial and commercial settings
• Versatile right-hand threading compatible with standard 8-32 UNC components for simplified inventory management

Professional Applications & Engineering Value

This 8-32 UNC brass thumb screw delivers critical solutions for frequent-access panels, electronic enclosures, and machinery covers where tool-less operation is essential. The knurled round head provides positive grip even with oily hands or gloves, reducing installation time while preventing slippage. Its low-profile design minimizes protrusion in tight spaces, while the fully threaded coarse pattern ensures rapid engagement and vibration resistance. The brass material offers natural corrosion resistance for humid environments, and the 50,000 psi tensile strength withstands repeated tightening cycles without deformation. Ideal for maintenance-intensive industrial equipment, telecommunications hardware, and laboratory instruments requiring reliable, quick-service fastening.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit ensuring consistent interchangeability. The UNC coarse thread (8-32) provides optimal performance in most materials, while the fully threaded 1/2" length offers maximum engagement depth. Compliant with RoHS 3 (2015/863/EU) regulations under exemption 6(c) for lead in copper alloys, meeting international environmental standards for industrial components.
