Professional Applications & Engineering Value
These black oxide steel rounded head screws deliver exceptional performance in industrial settings where corrosion resistance and mechanical reliability are paramount. The 12-24 UNC coarse thread configuration ensures rapid installation in metal assemblies, electrical enclosures, and machinery components, while the Phillips drive system provides familiar, efficient fastening for maintenance and production lines. The combination of 60,000 psi tensile strength and Rockwell B70 hardness makes these fully threaded screws ideal for applications subjected to vibration, thermal cycling, and mechanical stress. The black oxide surface treatment not only enhances corrosion protection but also provides consistent friction characteristics for precise torque control during assembly operations.
Specification Summary & Compliance
These rounded head screws feature precise Class 2A thread fit tolerances and are manufactured to ASME B18.6.3 specifications for dimensional accuracy and performance reliability. The UNC coarse thread with 12-24 thread size and right-hand thread direction ensures compatibility with standard industrial applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and material safety for global manufacturing requirements.
