- Maximum material compatibility with 0.025" maximum drilling thickness capability for versatile sheet metal applications
- Enhanced driving control with No. 0 Phillips drive style preventing cam-out and ensuring secure fastener installation
- Full-length threading with 48 TPI provides superior holding power across the entire fastener length
- Environmental compliance meeting RoHS 3 standards for safe, regulated use in global markets
Professional Applications & Engineering Value
These No. 1 Phillips flat head thread forming screws deliver exceptional engineering value in sheet metal applications where vibration resistance and permanent fastening are critical. The zinc-plated steel construction provides reliable corrosion protection while the thread forming design (A/AB type) creates stronger, more durable connections than conventional thread-cutting alternatives. The fully threaded 48 TPI configuration ensures maximum pull-out resistance, making these tapping screws ideal for HVAC systems, electronic enclosures, and automotive panels where material thickness typically ranges up to 0.025". The precision 82° countersink angle allows for flush mounting that eliminates snagging points and maintains aerodynamic surfaces.
Specification Summary & Compliance
These thread forming tapping screws feature a No. 1 screw size with 0.073" thread diameter and 1/4" length, manufactured to precise dimensional standards for consistent performance. The thread forming method follows industry-standard A/AB specifications with right-hand threading direction. Compliance with RoHS 3 (2015/863/EU) ensures environmental responsibility, while the recommended No. 52 drill bit (0.0635" diameter) ensures proper hole preparation for optimal thread engagement and holding strength in sheet metal applications.
