Professional Applications & Engineering Value
Engineered for precision industrial fastening applications, these 10-32 UNF zinc-plated steel screws deliver exceptional performance where fine thread engagement and corrosion resistance are critical. The fully threaded design ensures maximum holding power across varying material depths, while the Rockwell B70 hardness prevents thread deformation in high-cycle assembly operations. The rounded head profile with dual Phillips/Slotted drive accommodates diverse installation tools, making these screws ideal for electronics enclosures, machinery components, and commercial equipment where vibration resistance and long-term reliability are paramount. The fine thread spacing provides superior clamping force in metals and engineered plastics, addressing common challenges of loosening under dynamic loads.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 standards with Class 2A thread fit tolerance for precision engagement. Features 10-32 UNF fine threads with right-hand direction and fully threaded 1" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across regulated industries. The zinc-plated steel construction meets mechanical specifications including 60,000 psi tensile strength and Rockwell B70 hardness for consistent performance in demanding applications.
