Key Features & Benefits at a Glance
- Superior Thread Cutting Performance – Self-tapping Type F design creates precise threads in aluminum, brass, cast iron, and sheet metal without pre-threading, reducing installation time.
- Enhanced Corrosion Resistance – Zinc-plated steel construction provides reliable protection against rust and environmental exposure in industrial settings.
- Optimized Drive Efficiency – No. 2 Phillips drive ensures secure tool engagement and reduces cam-out risk during high-torque applications.
- Robust Coarse Thread Design – UNC 10-24 threading delivers excellent pull-out resistance and vibration resistance in softer materials.
- Full Thread Engagement – Fully threaded 1/4" length maximizes holding power across the entire fastener length.
- Standardized Pan Head Profile – Rounded head design with 0.373" diameter provides a professional finish and consistent seating surface.
- Industry Compliance Assurance – Meets ASME B18.6.3 and SAE J933 specifications for dimensional accuracy and mechanical performance.
Professional Applications & Engineering Value
These zinc-plated steel tapping screws solve critical fastening challenges in metal fabrication and assembly operations. The thread cutting Type F design eliminates the need for separate tapping operations when joining aluminum, brass, cast iron, and sheet metal components. The UNC coarse threading provides superior resistance to vibrational loosening while the Phillips drive system ensures efficient installation with standard tools. Engineered for demanding industrial applications, these screws maintain thread integrity even in thin materials, preventing stripping and ensuring long-term joint reliability in construction, machinery, and equipment assembly.
Specification Summary & Compliance
Manufactured to Class 2A thread tolerances with UNC 10-24 coarse thread specifications and compliant with ASME B18.6.3/SAE J933 standards. The zinc-plated steel construction meets industrial corrosion protection requirements while the fully threaded 1/4" length with 0.19" thread diameter ensures consistent performance. Recommended for use with No. 19 drill bit (0.166" diameter) for optimal thread formation in specified materials.
