Professional Applications & Engineering Value

Engineered for industrial equipment, electronic enclosures, and machinery panels, this 6-32 UNC thumb screw solves critical assembly challenges where frequent access or tool-free operation is essential. The 18-8 stainless steel material provides inherent corrosion resistance, eliminating degradation in humid or chemical-exposed environments. Its knurled head texture delivers maximum torque transmission during hand-tightening, while the coarse UNC thread profile maintains secure fastening against vibrations. The partially threaded shank allows precise clamping force control, making it ideal for access panels, calibration covers, and modular components requiring repeated maintenance cycles without thread wear concerns.

Specification Summary & Compliance

This thumb screw maintains Class 2A thread fit per UNC standards with precise 0.138" thread diameter and 7/16" thread length. Manufacturing follows standardized inch system measurements with 1/2" total length and 1/2" head height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency for industrial procurement.
