Professional Applications & Engineering Value
These 4-40 UNC coarse thread screws with black oxide steel construction address critical industrial fastening challenges where corrosion resistance and consistent performance are paramount. The rounded pan head design with Phillips drive provides a low-profile solution that withstands vibrational forces in machinery, electronics assembly, and automotive components. The Class 2A thread fit ensures smooth installation in both through-holes and tapped applications, while the fully threaded configuration maintains holding power across varying material thicknesses. Engineered to meet rigorous industrial screw requirements, these fasteners deliver reliable performance in environments where chemical exposure and mechanical stress would compromise standard fasteners.
Specification Summary & Compliance
Manufactured to exacting inch system dimensions with Class 2A thread fit tolerance per UNC standards. Complies with ASME B18.6.3 manufacturing specifications for dimensional consistency and performance reliability. Meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards. Thread specifications include 4-40 UNC coarse thread with right-hand threading direction and standardized pan head profile with 0.219" head diameter.
