Professional Applications & Engineering Value
These 12-24 UNC zinc-plated steel screws deliver exceptional engineering value through their coarse thread design and rounded pan head profile, specifically engineered to address common industrial fastening challenges. The zinc-plated steel construction provides superior corrosion protection in manufacturing environments, while the fully threaded configuration ensures maximum holding power across the entire 3/8" length. The No. 3 Phillips drive offers reliable installation with standard tools, reducing assembly time and preventing stripping. Ideal for industrial machinery, electrical enclosures, and equipment manufacturing, these screws maintain 60,000 psi tensile strength under vibration and dynamic loads, providing long-term reliability where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (12-24 size) and 0.216" thread diameter. Complies with ASME B18.6.3 manufacturing specifications for dimensional accuracy and performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. Features standard right-hand threading and fully threaded design with Rockwell B70 hardness certification.
