12G Self Tapping Stitch Screw 7/8 in

Description

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. Technical Specifications Product Type: Hex Head Self-Drilling Stitch Screw (Metal-to-Metal) Length: 7/8 inch Diameter: 12 Gauge (12G) 5/16 Head: The hexagonal head is compatible with standard socket wrenches Head Type: Hex Head with Bonded Neoprene Washer Thread Type: Fine/Medium (Optimized for Metal) Point Type: Self-Drilling Point Finish: Plated Steel (Galvanized/Zinc) Application: Overlapping Metal Sheets/Stitching, Metal Trim Grade: Construction/Exterior Roofing 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.
