Professional Applications & Engineering Value
These 12-24 UNC zinc-plated steel screws are engineered to address common industrial challenges, such as corrosion and mechanical stress in demanding settings. The zinc plating provides a protective barrier against moisture and chemicals, extending service life in outdoor or corrosive environments. With a coarse UNC thread and Class 2A fit, they facilitate rapid installation in materials like metal and wood, reducing assembly time and improving efficiency. The rounded pan head and Phillips drive ensure a flush, secure fit that resists loosening under vibration, making them ideal for machinery, automotive, and construction applications where reliability is critical. Their high tensile strength and hardness support heavy loads, preventing stripping and ensuring consistent performance in structural fastening.
Specification Summary & Compliance
This screw features precise Class 2A thread fit and UNC coarse threading with a diameter of 0.216" and length of 1-1/4", manufactured to ASME B18.6.3 standards for dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use.
