Itw Buildex 560047 Self Drilling Screw No. 12 Pack 100

Product Description

The ITW BUILDEX 560047 is a No. 12 self drilling screw designed for metal-to-metal and light structural fastening applications common in HVAC, mechanical, and general sheet metal work. Featuring a hex washer head with a hex drive, this screw measures 2 inches in length under the head and carries a No. 5 drill point, which provides the aggressive cutting geometry needed to penetrate heavier gauge steel without a pilot hole. Sold in a package of 100, the 560047 is a steel screw built to the inch measurement system with a No. 12-24 thread configuration. Licensed tradespeople and sheet metal installers turn to this fastener for secure, vibration-resistant connections in metal framing, ductwork, and mechanical enclosures.

This screw is suited for commercial and residential applications where a self-drilling fastener eliminates the need for a pre-drilled hole. The No. 5 drill point allows penetration of thicker steel stock compared to smaller point designations, making it a practical choice for structural steel framing, metal stud assemblies, equipment enclosures, and HVAC duct connections. The hex washer head bearing surface distributes clamping load and resists pull-through. HVAC technicians, sheet metal workers, and mechanical contractors typically carry this screw for field fabrication and equipment installation work.

Key Features

• No. 5 drill point for self-drilling into heavier gauge steel without a pilot hole
• No. 12-24 thread size for strong thread engagement in metal substrates
• Hex washer head provides a wide bearing surface and resists pull-through
• Hex drive accepts standard hex-shank power tool bits for fast installation
• 2 inches length under head suits a range of metal-to-metal fastening depths
• Package of 100 screws reduces reorder frequency on active job sites

Compatibility

Designed as an OEM-style replacement and standard fastener for sheet metal, light structural steel, and mechanical equipment enclosure applications requiring a No. 12 self drilling screw with a No. 5 drill point.

Installation Notes

Installation is performed with a hex-drive power screwdriver or impact driver set to a controlled torque to avoid stripping the hex washer head. Ensure mating surfaces are clean and free of debris before driving the screw. No pilot hole is required when the No. 5 drill point is used within its rated steel thickness range. Follow applicable building and mechanical codes, including SMACNA guidelines where duct connections are involved.
