Professional Applications & Engineering Value

This 6-32 UNC thumb screw delivers exceptional value in applications requiring frequent adjustments or tool-less operation. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for electronics, machinery panels, and outdoor equipment where moisture or chemicals are present. The knurled head ensures secure grip even with oily hands, reducing installation time and eliminating the need for additional tools. With its fully threaded coarse spacing and Class 2A thread fit, it offers reliable fastening in vibration-prone environments while maintaining precise alignment. The narrow profile round head design is particularly valuable in confined spaces where clearance is limited, providing engineers with a compact yet high-strength fastening solution that withstands repeated cycling without performance degradation.

Specification Summary & Compliance

This thumb screw features precision 6-32 UNC threads with Class 2A thread fit for consistent engagement and proper clearances. The coarse thread spacing (32 TPI) and 0.138" thread diameter provide optimal strength-to-size ratio. Manufacturing complies with industry standards for dimensional accuracy, and the product is certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental regulations for hazardous substance restrictions.
