Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Efficient self-tapping installation with Type F thread cutting design, eliminating the need for pre-tapped holes in materials like aluminum and brass.
- Enhanced driving stability provided by the Phillips No. 2 drive and pan head, reducing cam-out and ensuring secure fastening.
- Reliable coarse UNC threading (8-32) for quick assembly and strong holding power in sheet metal and cast iron applications.
- Full 3-inch length with complete threading offers maximum grip range and consistent performance across varied material thicknesses.
- Compliance with ASME B18.6.3 standards guarantees dimensional accuracy, interchangeability, and consistent quality for industrial use.
- Broad material compatibility for use in aluminum, brass, cast iron, and sheet metal, reducing inventory needs for multiple applications.
Professional Applications & Engineering Value
This zinc-plated steel tapping screw is engineered to address common challenges in metal assembly, such as stripping, corrosion, and inconsistent thread formation. The Type F thread cutting design and coarse UNC thread spacing enable clean, secure threads in ductile materials like aluminum, brass, and sheet metal, minimizing the risk of material fatigue. The Phillips drive and pan head provide controlled torque application, which is critical for automated or high-volume production lines. Ideal for construction, HVAC, and automotive industries, these screws ensure reliable fastening without secondary tapping, saving time and labor costs while maintaining ASME B18.6.3 compliance for safety and performance.
Specification Summary & Compliance
This screw features a No. 8-32 UNC coarse thread with a diameter of 0.164" and a length of 3", fully threaded for uniform engagement. It adheres to ASME B18.6.3 and SAE J933 specifications, ensuring precise dimensional tolerances (e.g., Class 2A fit) and consistent performance. The zinc-plated finish provides corrosion resistance, and the product is designed for use with a No. 20 drill bit (0.147" diameter). Compliance with industry standards guarantees reliability in thread cutting applications for metals including cast iron and sheet metal.
