Simpson Strong-Tie #8 x 2-1/4" Self-Drilling Square Drive Fiber-Cement Screw, Square Wafer Head - 410 Stainless Steel, Qty. 100
Specifications
When you need a fast, precise fastening solution to secure fiber-cement board or panel overlays to steel framing without pre-drilling, this Simpson Strong-Tie F08T225WDC Self-Drilling Fiber Cement Screw delivers. Engineered with a sharp self-drilling point, a wafer-style head with self-countersinking nibs, and built from heat-treated Type 410 stainless steel, it offers reliable performance in demanding applications. Ideal for wood or panel substrates over steel studs, it brings speed, strong engagement and a clean finish.
Key Features
- Wafer Head Design: Features self-countersinking nibs under the head for a clean flush finish.
- Extended Thread Length: Threading reaches within 5/16" of the head to improve embedment and pull-through resistance.
- Self-Drilling #3 Point: Penetrates steel without pre-drilling, designed for light-gauge metal framing.
- Drive System: Compatible with #2 square-drive bits for consistent tool performance and stability.
- Durable Material: Constructed from Type 410 stainless steel with protective coating for enhanced corrosion resistance.
Applications
- Attaching fiber-cement board, plywood or sheathing to cold-formed steel studs and tracks.
- Installing furring strips or other panel systems to light-gauge steel framing.
- Interior and protected exterior applications where a flush finish and durable corrosion protection are required.
- Commercial build-outs, remodels, retrofit panel work and other steel-to-panel structural connections.
Installation
- Select the correct screw length and diameter for the application, ensuring the drill point penetrates the steel and the threads fully engage the panel substrate.
- Use a power driver with a #2 square-drive bit. Adjust torque settings to avoid over-driving or damaging the screw head.
- Drive the screw perpendicular to the panel surface until the wafer head sits flush with the material face.
- Verify that the steel thickness and material compatibility are appropriate for Type 410 stainless steel. In exposed areas, confirm corrosion protection requirements are met.
- Follow manufacturer recommendations for spacing, pattern, and panel support to maintain structural code compliance.
- Use recommended driving speed and method for self-drilling screws to ensure efficient and accurate installation.

The Right Point for Every Project
Different point types pierce various materials. Standard points handle light- to medium-gauge metal, long points tackle thicker steel, self-piercing points work well in wood or thin metal and winged points clear softer layers before drilling harder substrates, ensuring faster, cleaner and secure installations.
