Professional Applications & Engineering Value

This 1/4"-20 brass thumb screw delivers exceptional value in applications requiring frequent adjustments or tool-free operation. The spade head design enables rapid manual tightening in confined spaces where traditional tools cannot reach, significantly reducing assembly time in electronics, instrumentation, and machinery maintenance. The brass material provides natural corrosion resistance while the UNC coarse threads offer faster installation and reduced cross-threading risks compared to fine threads. With fully threaded construction and Class 2A thread fit, engineers benefit from consistent engagement depth and reliable performance in vibration-prone environments. The combination of 50,000 psi tensile strength and Rockwell B40 hardness ensures these thumb screws maintain integrity under repeated use cycles.

Specification Summary & Compliance

This thumb screw features 1/4"-20 UNC coarse threads with Class 2A thread fit for standard inch-system applications. The right-hand thread direction and fully threaded 1" length provide complete fastening coverage. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring material safety and regulatory compliance for industrial and commercial use.
