Professional Applications & Engineering Value
These Black-Oxide 18-8 Stainless Steel rounded head screws deliver critical performance where corrosion resistance and mechanical reliability are paramount. The coarse UNC threading ensures rapid installation and superior grip in softer materials or high-vibration environments, while the fully threaded design maximizes load distribution across the entire fastener length. Engineers specify these pan head screws with Phillips drive for electrical enclosures, machinery assemblies, and outdoor equipment where the combination of 70,000 psi tensile strength and chemical-resistant coating prevents premature failure. The Class 2A thread fit maintains precise tolerances for consistent clamping force without galling or cross-threading issues common in production environments.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 standards with Class 2A thread fit precision. The 12-24 UNC coarse thread pattern maintains dimensional accuracy per inch-system requirements. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmentally responsible manufacturing. Mechanical properties include verified 70,000 psi tensile strength and Rockwell B70 hardness for consistent performance across industrial applications.
