Malco BT142 Bit-Tip Drill and Tap Screws are engineered to transform HVAC installation and metal fabrication. With a dedicated #2 point and 10-16 x 5/8" dimensions, these screws are built to drill, tap, and fasten in a single, decisive pass.

Designed for one-pass fastening, the Bit-Tip screws create the optimal hole size as they bite, delivering superior thread engagement and a tighter, more secure fit. That means fewer alignment issues and less time spent on multi-step fastening—ideal for busy job sites and demanding assemblies.

• One-step drilling, tapping and fastening: eliminates the need for separate drill bits, taps, rivets, nuts and bolts, spot welds, or adhesives.
• Self-drilling and self-tapping action: stock your toolbox with fewer tools while expanding your fastening options across metals and prepared materials.
• Point length and material versatility: the point length determines the metal thickness you can drill, tap, and fasten, while the screws also accommodate plywood, soft wood, composition board, drywall, insulation, and laminates when anchoring to metal framing.
• Premium construction: forged from strong, heat-treated steel and precision cold-forged for uniform dimensions and drill-point contours, ensuring consistent performance batch after batch.
• Structural & layered metal ready: specifically suited for HVAC fasteners and structural applications in metal framing, ductwork, and layered metal assemblies.
• Optimal head design: 5/16" hex washer head provides a secure, flush seating that resists pull-out in challenging environments.
• Bulk value: available in an 8000-count carton, delivering cost-effective stocking for large projects and continuous work flows.
• Easy to use: requires only a standard screw gun rated at 2500 RPM with a drilling depth locator—no specialized equipment needed.

Who benefits most: HVAC installers, metal fabricators, contractors, and DIY enthusiasts tackling metal-to-metal or metal-to-wood assemblies where speed, accuracy, and reliability matter. In scenarios where traditional rivets, nuts and bolts, or spot welds are common, Malco BT142 Bit-Tip screws offer a cleaner, faster, and more versatile alternative.

Practical tips for best results: match the screw length (5/8") to your metal thickness, rely on the Bit-Tip to determine the hole size, and use a depth locator to prevent over-penetration. For projects involving metal framing with adjacent materials like drywall or plywood, these screws simplify installation and improve overall fastening integrity.
