Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
  • Efficient thread-forming design that creates strong, secure threads in steel and sheet metal without pre-drilling, saving time and labor costs.
  • Integrated No. 3 drill tip allows for easy penetration and drilling through materials up to 0.21" thick, reducing the need for separate pilot holes.
  • Standard oval head with 82° countersink angle provides a flush, professional finish that minimizes snagging and improves aesthetic appeal.
  • Phillips drive (No. 3 size) ensures reliable torque transmission and reduces the risk of cam-out during installation for consistent fastening.
  • Fully threaded shank offers maximum grip and holding power across the entire length, enhancing joint integrity in demanding applications.
  • Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in global industrial and construction projects.

Professional Applications & Engineering Value

These 1/4"-14 zinc-plated steel oval head tapping screws are engineered to address common challenges in metalworking, such as material fatigue and installation inefficiency. The thread-forming (BSD) design eliminates the need for tapped holes, reducing assembly steps and minimizing the risk of thread stripping in steel and sheet metal applications. The zinc-plated finish provides a durable barrier against rust and corrosion, extending service life in outdoor or high-moisture environments. With a No. 3 drill tip and precise 82° countersink angle, these screws ensure quick, flush mounting in HVAC systems, automotive panels, and structural frameworks, delivering reliable performance that meets rigorous industrial standards.

Specification Summary & Compliance

This product features a 1/4" thread diameter with 14 threads per inch, conforming to standard inch measurements for consistent fit. The thread-forming tapping method (BSD type) and fully threaded right-hand design ensure accurate engagement and high pull-out strength. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, these screws adhere to environmental and safety regulations, making them suitable for global industrial use without hazardous substances.
