Malco BT144G 10-16 x 1 Bit-Tip #3 Point Self-Tapping & Self-Drilling Sheet Metal Screws- 5/16" Hex Washer Head | HVAC Fastners | Structural & Layered Metal (100 Count)

Malco BT144G 10-16 x 1 Bit-Tip #3 Point Self-Tapping & Self-Drilling Sheet Metal Screws are purpose-built for quick, dependable fastening in HVAC, structural, and layered metal applications. By drilling its own hole, Bit-Tip creates the optimal hole size for superb thread engagement and a tight, secure fit—every time.

One-pass fastening means fewer steps and fewer alignment problems. The Bit-Tip design combines drilling, tapping, and driving in a single operation, so you can move faster on installations from ductwork to metal framing without juggling drill bits, taps, rivets, nuts, bolts, or spot welds.

• Self-drilling and self-tapping performance: The Bit-Tip Point geometry drills the hole and forms threads in one motion, maximizing grip in metal while reducing prep work.
• Precise size and uniformity: Precision cold-forged steel delivers consistent dimensions and drill-point contours for dependable seating and repeatable results.
• Broad material compatibility: In addition to metal, these screws can fasten to plywood, soft wood, composition board, drywall, insulation, and laminates when mounting to metal framing or components.
• Versatile finish for HVAC and structural work: The 5/16" hex washer head provides a robust, flush seating surface ideal for HVAC ducting, metal studs, and layered metal assemblies.
• RVI-friendly replacement for multiple fasteners: Replace rivets, nuts and bolts, spot welds, or adhesives with a single, reliable screw that holds tight under vibration and load.
• Tool-ready: Uses a standard screw gun rated up to 2500 RPM with a drilling depth locator, eliminating the need for specialized equipment.
• Quality you can trust: Made from strong, high-quality, specially heat-treated steel to withstand demanding HVAC and metal-working environments.

What you can fasten

• HVAC ductwork, metal panels, and insulated metal assemblies
• Structural and layered metal components, including metal framing and studs
• Materials such as plywood, soft wood, composition board, drywall, and laminates when joining to metal framing

How the BT144G works in practice

• Choose the Bit-Tip screw for the metal thickness you’re working with—the point length determines how thick the metal can be drilled, tapped, and fastened.
• Load the screw into the screw gun with the depth locator set to your desired bite depth.
• Position at the fastening point; apply steady pressure and let the Bit-Tip drill, thread, and seat in one smooth pass.
• Drive to the required depth and stop—no secondary tapping or drilling steps needed.

Ideal for professionals and serious DIYers

• HVAC installers seeking fast, reliable metal-to-metal and metal-to-wood connections
• Contractors working with metal framing and layered metal systems
• Anyone replacing rivets or bolts with a cleaner, more efficient fastening solution
