Professional Applications & Engineering Value
This zinc-plated steel thumb screw delivers critical advantages for industrial applications where tool-free access and reliable fastening are paramount. The spade head design provides substantial surface area for comfortable hand-tightening, eliminating the need for tools in confined spaces or during frequent maintenance cycles. Engineered with UNC coarse threads and Class 2A thread fit, these thumb screws ensure rapid installation with reduced risk of cross-threading while maintaining secure connections in vibration-prone equipment. The combination of 40,000 psi tensile strength and Rockwell B55 hardness creates an optimal balance between durability and machinability, making these fasteners ideal for machinery panels, electrical enclosures, and assembly jigs where repeated adjustments are necessary without compromising structural integrity.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent performance across applications. Features UNC 5/16"-18 coarse thread spacing with right-hand threading direction and full threading along the 2" length. Compliant with RoHS 3 (2015/863/EU) regulations, ensuring environmental responsibility while meeting industrial fastening requirements for zinc-plated steel components.
