Key Features & Benefits at a Glance
- Enhanced corrosion resistance with zinc-plated steel construction for reliable performance in industrial environments
- Superior thread-forming capability creates strong, permanent threads in sheet metal without pre-tapping
- Optimal flush installation with standard flat head profile and 82° countersink angle for smooth surface finishing
- Efficient driving performance through Phillips No. 2 drive design that reduces cam-out during installation
- Maximum material engagement with fully threaded design ensuring consistent holding power across the entire length
- Precision compatibility with No. 29 drill bit (0.136" diameter) for accurate hole preparation in sheet metal up to 0.025" thickness
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe industrial use
Professional Applications & Engineering Value
These thread forming tapping screws deliver exceptional value in sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides durable corrosion protection while the A/AB tapping screw design with 15 threads per inch creates secure, vibration-resistant connections without requiring pre-tapped holes. The fully threaded configuration ensures maximum pull-out resistance, making these Phillips flat head fasteners ideal for HVAC systems, electrical enclosures, and metal fabrication where flush mounting is essential. The 82° countersink angle allows for proper seating in prepared holes, preventing surface protrusion while maintaining structural integrity in thin-gauge materials.
Specification Summary & Compliance
This No. 8-15 x 3/4" tapping screw features precise dimensional specifications including 0.164" thread diameter and standard inch measurements. Manufactured as a thread forming fastener with right-hand threading and pointed tip for easy starting. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. Designed specifically for use with No. 29 drill bits in sheet metal applications requiring reliable, permanent fastening solutions.
