Professional Applications & Engineering Value
These 10-32 UNF thumb screws deliver exceptional value in applications requiring frequent adjustments or tool-free operation. The steel construction with Rockwell B55 hardness ensures durability against repeated use, while the fully threaded design provides maximum holding strength across the entire 2-inch length. The spade head shape offers superior ergonomics for quick hand-tightening in industrial equipment, electronic enclosures, and machinery access panels. The fine thread spacing and Class 2A thread fit maintain precise alignment and vibration resistance in right-hand thread applications, solving common issues of loosening under dynamic loads. These RoHS 3 compliant fasteners meet stringent environmental standards without compromising mechanical performance.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit ensuring interchangeability in UNF thread systems. The 10-32 thread size features fine thread spacing with 0.19" thread diameter and right-hand orientation. Compliant with RoHS 3 (2015/863/EU) regulations, these screws meet international environmental standards while maintaining 40,000 psi tensile strength and Rockwell B55 hardness specifications for reliable industrial performance.
