Product Description
The Simpson #8 x 3/4 in. Collated Pan Head Framing to CFS Screw is a self-drilling fastener from Simpson built specifically for cold-formed steel framing applications. With an 18 TPI thread pattern, a #2 drill point, and straight collation engineered for use with the Quik Drive PROPHG2 auto-feed system, this screw is designed to handle the repetitive demands of steel-to-steel fastening in structural framing work without pre-drilling or slowdowns at the gun.
Key Features
- Pan head design - sits flush and low-profile against cold-formed steel surfaces, creating a secure, stable connection without protruding hardware
- #2 square drive - provides positive bit engagement and reduces cam-out during high-speed installation, keeping work moving and reducing stripped fasteners
- #2 drill point - self-drills into cold-formed steel without pre-drilling, saving time and eliminating an extra tool step on the job
- 18 TPI thread pattern - optimized for gripping cold-formed steel framing members and sheet steel sheathing with consistent thread engagement
- Yellow-zinc coating - provides a layer of corrosion resistance suited to steel framing environments
- Straight collation compatible with the Quik Drive PROPHG2 - integrates directly with the auto-feed driving system for faster, more consistent screw placement across large framing runs
Why This Product
- No pre-drilling required - the #2 drill point penetrates cold-formed steel on contact, cutting out a time-consuming step and letting crews drive more fasteners per hour on steel framing jobs
- Purpose-built for cold-formed steel framing - every design element, from the 18 TPI thread to the pan head profile, is matched to the demands of fastening CFS framing and sheet steel sheathing to cold-formed steel structural members
- Auto-feed system compatibility - straight collation and Quik Drive PROPHG2 compatibility mean these screws work seamlessly with a system built for high-volume production framing, reducing fatigue and improving placement consistency
- Trusted Simpson engineering - backed by a brand with a long record in structural connectors and fasteners, giving builders and inspectors confidence in the fastener choice for cold-formed steel applications
