Key Features & Benefits at a Glance
- Enhanced corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
- Superior holding power thanks to the integrated flange design that eliminates the need for separate washers
- Efficient thread forming in sheet metal applications creates strong, permanent threads without pre-tapping
- Quick and secure installation with the pointed tip design and square drive (No. 2) preventing cam-out
- Optimized for sheet metal with precise compatibility for No. 29 drill bits and 0.025" maximum drilling thickness
- Full-length threading ensures maximum grip along the entire 1" length for superior fastening strength
- Reliable performance meeting A/AB tapping screw standards with consistent 15 threads per inch for uniform clamping force
Professional Applications & Engineering Value
These zinc-plated steel flanged tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design creates precise, durable threads in parent material without generating chips, eliminating cleanup and ensuring secure fastening in thin-gauge applications. The pan head with integrated flange provides superior load distribution while the fully threaded construction maintains consistent clamping force across the entire engagement length. Engineered for use with standard No. 29 drill bits, these right-hand threaded screws streamline installation processes in HVAC systems, electrical enclosures, and automotive panels where vibration resistance and corrosion protection are critical.
Specification Summary & Compliance
This No. 8 x 1" tapping screw features a 0.164" thread diameter with 15 threads per inch, manufactured to A/AB tapping screw standards for consistent performance. The screw demonstrates precise dimensional accuracy with a 0.361" flange diameter and 0.113" head height. The zinc-plated steel construction provides corrosion resistance while the thread forming design ensures reliable fastening in sheet metal up to 0.025" thickness. Compliant with industry standards for mechanical properties and surface treatment requirements.
