Professional Applications & Engineering Value

These black-oxide steel thumb screws solve critical industrial fastening challenges where tool-free access and durability are paramount. The knurled head texture provides maximum hand grip for rapid assembly/disassembly in maintenance panels, electronic enclosures, and machinery guards. With fully threaded UNC coarse spacing, they deliver faster installation and superior holding power in wood, metal, and plastic applications. The low-profile round head design prevents snagging while the right-hand thread direction ensures intuitive operation. Engineered for industrial thumb screw applications requiring frequent adjustments, these fasteners maintain 70,000 psi tensile strength under repetitive use, making them ideal for production equipment, aerospace components, and telecommunications infrastructure where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance and UNC thread specifications. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead as an alloying element in steel and REACH (EC 1907/2006) regulations. The 10-24 thread size with coarse spacing ensures broad compatibility with standard components while the 1½" length provides versatile fastening depth options for various material thicknesses.
