Professional Applications & Engineering Value
Engineered for industrial equipment maintenance and frequent-access panels, this zinc-plated steel thumb screw solves critical assembly challenges where tool-less operation is essential. The spade head design offers exceptional torque application capability, while the coarse UNC threading (3/8"-16) resists cross-threading during rapid installations. The integrated flange eliminates the need for separate washers, distributing clamp force evenly across surfaces and preventing material deformation. With fully threaded construction and right-hand direction, this fastener maintains consistent holding power in vibration-prone machinery, electrical enclosures, and production line equipment where repeated adjustments are necessary.
Specification Summary & Compliance
This thumb screw features precision Class 2A thread fit with UNC coarse threading (3/8"-16) manufactured to standard inch system specifications. The 0.688" flange diameter and 3/4" length provide optimal dimensional stability. Compliance with RoHS 3 (2015/863/EU) ensures environmental responsibility, while the 40,000 psi tensile strength and Rockwell B55 hardness verify mechanical performance for industrial applications.
