Key Features & Benefits at a Glance
- Self-tapping design eliminates the need for pre-tapped holes, reducing installation time and labor costs in materials like aluminum, brass, and cast iron.
- Black zinc-plated steel construction provides enhanced corrosion resistance, ensuring long-term durability in industrial environments.
- UNC coarse threading offers faster installation and superior holding power in softer metals and sheet metal applications.
- Phillips pan head with No. 2 drive allows for secure tool engagement and a low-profile finish that minimizes snagging.
- Fully threaded shank ensures consistent grip along the entire length, maximizing pull-out strength in various material thicknesses.
- ASME B18.6.3 compliance guarantees consistent quality, dimensional accuracy, and reliability for critical assembly operations.
- Optimized for No. 31 drill bit (0.12" diameter) to ensure precise fit and reduced risk of material stripping during thread cutting.
Professional Applications & Engineering Value
These Type F tapping screws are engineered to solve common fastening challenges in metalworking and construction. The thread-cutting design creates precise mating threads in ductile materials like aluminum, brass, cast iron, and sheet metal, eliminating the need for separate tapping operations and reducing assembly time. The black zinc-plated steel finish provides a protective barrier against oxidation and wear, extending service life in demanding conditions. With UNC coarse threads and a blunt tip, these screws deliver rapid installation and high resistance to vibration loosening, making them ideal for HVAC systems, electrical enclosures, and machinery frames where reliability is critical.
Specification Summary & Compliance
This screw meets ASME B18.6.3 specifications, ensuring dimensional accuracy with a 6-32 UNC coarse thread, 1/2" length, and standard Class 2A thread fit. It is designed for use with a No. 31 drill bit (0.12" diameter) and features a right-hand thread direction and fully threaded shank. The black zinc-plated surface treatment complies with RoHS and REACH environmental standards, providing corrosion resistance without hazardous substances.
