Professional Applications & Engineering Value
These black oxide steel pan head screws deliver exceptional performance in industrial settings where corrosion resistance and mechanical strength are critical. The 2-56 UNC coarse thread configuration ensures rapid installation and secure fastening in materials requiring coarse pitch threading, while the fully threaded design maximizes grip length for enhanced load distribution. The #1 Phillips drive provides reliable torque transmission without cam-out issues, making these rounded head screws ideal for assembly lines requiring efficiency and consistency. Engineered to withstand vibration and mechanical stress, these components serve perfectly in electronics enclosures, machinery panels, and automotive assemblies where Class 2A thread fit guarantees precise engagement and long-term reliability.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerances ensuring dimensional accuracy and interchangeability. The black oxide steel construction provides consistent performance with 60,000 psi tensile strength and Rockwell B70 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, these screws meet the highest standards for industrial use while maintaining UNC coarse thread specifications for universal compatibility.
