Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments.
- Efficient self-tapping installation with Type F thread cutting design, eliminating the need for pre-tapped holes in materials like aluminum and cast iron.
- High torque transmission and reduced cam-out via No. 3 Phillips drive, ensuring secure and reliable fastening.
- Excellent material compatibility with coarse UNC threads, providing strong holding power in aluminum, brass, cast iron, and sheet metal.
- Full 1-inch threading for maximum grip and uniform stress distribution along the entire fastener length.
- Standard pan head profile offers a low-profile, rounded finish for smooth surface integration and enhanced aesthetics.
- Compliance with ASME B18.6.3 and SAE J933 standards guarantees consistent quality, dimensional accuracy, and performance reliability.
Professional Applications & Engineering Value
These 12-24 UNC tapping screws are engineered to address common assembly challenges in metalworking and fabrication. The zinc-plated steel material provides a durable barrier against oxidation, while the thread cutting (Type F) design allows for direct installation into ductile metals without pre-threading, reducing labor time and tooling costs. The coarse thread spacing and fully threaded shank ensure rapid engagement and high pull-out resistance in aluminum, brass, cast iron, and sheet metal applications. Ideal for HVAC systems, automotive panels, and machinery enclosures, these screws deliver consistent performance where vibration resistance and long-term fastener integrity are critical.
Specification Summary & Compliance
This product adheres to UNC thread standards with a 12-24 thread size and coarse spacing, ensuring compatibility with standard drill bits (No. 11, 0.191" diameter). Manufactured in accordance with ASME B18.6.3 and SAE J933 specifications, these screws maintain precise dimensional tolerances for reliable performance. The zinc plating finish meets common industry requirements for corrosion protection, and the product is suitable for use in environments requiring consistent mechanical properties and fastener reliability.
