12G Self-Tapping Stitch Screw 7/8”

12G Self-Tapping Stitch Screws – Watertight Seal, High Strength for Metal-to-Metal Overlap

These 12G Self-Tapping Hex Head Stitch Screws are specialized, heavy-duty fasteners essential for connecting overlapping metal panels in exterior applications. The 12 Gauge diameter provides superior shear strength, and the short 7/8 inch length is perfectly designed for securely stitching two thin sheets of metal together.

The Self-Drilling Tip eliminates the need for pre-drilling through the metal, greatly accelerating installation time. The screw features a Hex Head and an integrated bonded neoprene washer, which compresses during driving to create a durable, watertight seal around the screw hole, effectively preventing leaks at the seam and inhibiting corrosion. They are ready for high-volume use.

Key Benefits

• Heavy Duty 12G: Provides superior shear strength and durability for metal-to-metal connections.

• Watertight Seal: Bonded neoprene washer seals the overlap connection, preventing water ingress at the seam.

• Self-Tapping Efficiency: Tek tip drills its own pilot hole through thin metal, accelerating installation (no pre-drilling).

• Corrosion Resistance: Plated hex head and shank offer strong protection against exterior weather elements.

• Ideal Short Length: 7/8″ length is perfect for joining two thin metal sheets without excessive protrusion beneath.

Perfect For

• Stitching corrugated metal roofing/siding sheets together at the seam.

• Securing metal ridge caps, flashing, and trim pieces to the underlying panels.

• Exterior construction requiring a guaranteed watertight seal.

• High-volume, quick metal-to-metal fastening.

Application Instructions

• Driving: Use a variable speed drill equipped with a correct size hex driver bit.

• Setting: Drive the screw straight through both metal layers.

• Tightening: Stop driving immediately when the neoprene washer is visibly compressed and sealed against the panel. Do not over-tighten or crush the neoprene.

• Safety: Wear safety glasses during installation.

Pro Tips

• Always check the gauge of the metal; the Tek tip is designed for light-to-medium gauge steel (e.g., 20-26 gauge).

• Do not over-tighten, as crushing the neoprene will cause the seal to fail prematurely.

• Clean off any metal shavings immediately after drilling to prevent rust spots on the panel.

• Use a magnetic bit holder for efficient high-volume fastening.
