The Simpson FPH Flat Pan-Head Screw (#10 x 3/4 in., T20, Clear Zinc) is engineered by Simpson specifically for precision steel roll-forming technology - the dimpled steel stud fastening method used by manufacturers such as FRAMECAD, Howick, Arkitech, Pinnacle Structures, and Scottsdale Construction Systems. Its sharp point and tapping thread design deliver instant starts and consistent holding power in light-gauge steel framing, while the deeper flat pan head seats flush within dimpled steel studs for a clean, secure connection every time. This 5,000-count bulk package includes one T20 driver bit, making it a ready-to-deploy solution for high-volume roll-formed steel construction.

Key Features

• Sharp point for fast starts in prepunched steel framing - eliminates the need for pre-drilling and keeps work moving efficiently on roll-formed steel stud applications.
• Deeper, stronger flat pan head fits flush within the dimpled steel studs - ensures a low-profile, flush seat that aligns perfectly with roll-formed dimple geometry and maintains a clean framing surface.
• Aligns with prepunched holes - designed to index accurately into factory-punched stud holes, reducing mislocation and rework during steel framing assembly.
• 18 threads per inch tapping thread design - delivers consistent, reliable holding power in light-gauge steel without relying on a pre-tapped hole.
• Deep T20 6-lobe recess - reduces driver bit wear and provides a more secure bit-to-screw engagement, minimizing cam-out and stripping on the job.
• Eliminates stripping in light-gauge steel - the combination of sharp point, tight thread pitch, and T20 drive geometry keeps the screw on track from start to finish.
• Clear zinc coating - provides a corrosion-resistant finish suited to interior steel framing environments.
• Driver bit included - a T20 driver bit ships with every 5,000-count package so crews can get to work immediately; replacement bit model BIT20T-2-R2 is available separately.

Why This Product

• Built for roll-formed steel framing systems specifically - unlike general-purpose self-drilling screws, the FPH screw is purpose-designed for the dimpled steel stud fastening method used by leading roll-forming system manufacturers, making it the correct mechanical fit rather than a workaround.
• The flat pan head and sharp point work together as a system - the head geometry seats flush in the dimple while the sharp point self-starts in prepunched holes, eliminating two common sources of delay and error in light-gauge steel assembly.
• Less downtime from bit wear and cam-out - the deep T20 6-lobe recess keeps the driver bit firmly engaged throughout the drive cycle, reducing the stripping and bit replacement that slow down high-volume steel framing work.
• Bulk quantity with everything needed to start - the 5,000-count package includes a T20 driver bit, so crews handling large-scale roll-formed steel framing projects have the fasteners and tooling on hand without a separate order.

Frequently Asked Questions

What type of steel framing systems are these screws designed for?

The Simpson Strong-Tie FPH Flat Pan-Head Screw is designed specifically for precision steel roll-forming technology - the dimpled steel stud fastening method used by manufacturers such as FRAMECAD, Howick, Arkitech, Pinnacle Structures, and Scottsdale Construction Systems. The screw aligns with prepunched holes in roll-formed steel studs and the flat pan head seats flush within the dimpled profile.

What driver bit is required, and is one included?

These screws require a T20 6-lobe driver bit. One driver bit is included with this 5,000-count package. If you need a replacement, the compatible replacement bit model is BIT20T-2-R2.

How does the head and thread design prevent stripping in light-gauge steel?

The FPH screw features a deep T20 6-lobe recess that reduces driver bit wear and provides a more secure driving connection, which helps eliminate cam-out and stripping. The 18 threads per inch tapping thread design delivers consistent holding power, and the sharp point allows fast, precise starts in prepunched steel framing without slipping.

What are the key specifications for this screw?

This screw is a #10 size with a 3/4 in. length, a flat pan head with a 0.340 in. head diameter, T20 6-lobe drive, tapping threads at 18 threads per inch, and a sharp point. It features a clear zinc coating for corrosion resistance. This package contains 5,000 screws.
