Professional Applications & Engineering Value
These black oxide steel rounded head screws deliver exceptional engineering value in industrial applications where corrosion resistance and mechanical reliability are critical. The combination of 8-32 UNC coarse threading and Class 2A thread fit ensures quick installation and secure fastening in metal assemblies, machinery, and equipment frames. The pan head profile with No. 2 Phillips drive provides a low-profile solution that resists stripping during high-torque applications. With full threading along the entire 3 1/4" length, these screws maintain consistent clamping force across thick materials, preventing joint failure in heavy-duty industrial applications while meeting stringent quality standards.
Specification Summary & Compliance
These screws feature Class 2A thread fit with UNC coarse threading (8-32 size) and precise dimensional compliance with ASME B18.6.3 manufacturing standards. The product meets environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring they contain no restricted substances. Manufacturing specifications include right-hand threading, fully threaded design, and standard pan head profile with 0.322" head diameter and 0.115" head height for consistent performance across industrial applications.
