Meet Malco BT143P #2 Point 10-16 x 3/4" Bit-Tip Drill and Tap Screws — the HVAC fasteners designed for metal-heavy builds and layered assemblies.

By drilling its own hole, Bit-Tip creates the optimum hole size for better thread engagement and a tighter, more secure fit. One-operation fastening means no misalignment or fiddling with multiple tools, speeding up installations and reducing on-site surprises.

Why Malco BT143P stands out

• Self-drilling and self-tapping action handles metal thickness with the point length 10-16 x 3/4", eliminating the need for separate drill bits or taps.
• One-step fastening accelerates assemblies, particularly in HVAC ductwork, metal framing, and structural metal projects, where precision and speed matter.
• 5/16" hex washer head ensures secure seating, clean finish, and strong load distribution even on busy job sites.
• Durable construction crafted from high-quality, specially heat-treated steel and precision cold-forged for uniform dimensions and consistent drill-point contours.
• Versatile substrate compatibility capable of fastening plywood, soft wood, composition board, drywall, insulation, and laminates to metal framing or components—ideal for mixed-material assemblies common in HVAC and building projects.
• Rivets, nuts and bolts, spot welds or adhesives—take a backseat as Bit-Tip serves as a practical replacement in many fastening operations, simplifying inventory and tooling needs.
• Simple tool requirements works with a standard screw gun up to 2500 RPM and a drilling depth locator, making installation approachable for pros and seasoned DIYers alike.
• Bulk-ready packaging available in a 3000-piece pail, keeping crews stocked for large-scale HVAC and metalwork projects.

Whether you’re installing ductwork, mounting metal panels, or fastening layered metal components, the Malco BT143P delivers one-tool efficiency, reliable performance, and a streamlined workflow that helps you finish jobs faster with fewer interruptions.
