Professional Applications & Engineering Value
This 10-24 UNC thumb screw delivers exceptional value in applications requiring frequent adjustments or tool-less access. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making it ideal for electronics enclosures, machinery guards, and laboratory equipment where corrosion could compromise performance. The spade head design offers superior ergonomics for hand-tightening operations, reducing operator fatigue in high-cycle applications. With fully threaded coarse UNC threads and Class 2A fit, these screws maintain reliable engagement in both metallic and non-metallic materials, preventing cross-threading while ensuring consistent clamping force. The right-hand thread configuration follows industry standards for intuitive installation across manufacturing, maintenance, and assembly lines.
Specification Summary & Compliance
This thumb screw features precision 10-24 UNC coarse threads with Class 2A thread fit per ASME B1.1 standards, ensuring consistent dimensional accuracy and reliable performance. The fastener is fully threaded along its 3/8" length with right-hand direction for standard installation. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial applications.
