Professional Applications & Engineering Value
This black oxide steel rounded head screw delivers exceptional engineering value for industrial assembly applications where corrosion resistance and mechanical reliability are paramount. The 10-24 UNC coarse threading with Class 2A fit provides rapid installation and secure fastening in materials ranging from steel to aluminum assemblies. The pan head design with Phillips No. 2 drive offers a balanced profile for applications requiring moderate clearance while ensuring positive driver engagement. Engineered for machinery, equipment manufacturing, and structural frameworks, these fully threaded screws distribute clamping force evenly across the entire 2 1/4" length, preventing joint loosening under vibration and thermal cycling conditions common in industrial environments.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 2A thread fit tolerance per UNC standards. Complies with ASME B18.6.3 mechanical and dimensional specifications for slotted and recessed head screws. Meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations for chemical safety. Features right-hand thread direction with coarse thread spacing optimized for rapid assembly in industrial applications.
