Malco BT142G #2 Point 10-16 x 5/8" | Bit-Tip Drill and Tap Screws | 5/16" Hex Washer Head | HVAC Fastners | Structural & Layered Metal | Self Tapping and Self Drilling Sheet Metal Screws, 100 Bag

Meet the Malco BT142G Bit-Tip Drill and Tap Screws—the all-in-one fastening solution designed for HVAC, structural, and layered metal applications. With Bit-Tip intelligence built into every fastener, you’re guaranteed a precise hole and a secure thread every time.

One-step drilling and tapping means you drill, tap, and fasten in a single motion. The Bit-Tip point creates the optimum hole size as it penetrates metal, delivering superior thread engagement and a tighter, vibration-resistant fit. That means fewer misalignments, faster assemblies, and cleaner, more professional results on every project.

The BT142G is engineered for versatility across materials. While optimized for metal, its point length is designed to determine the metal thickness you can drill, tap, and fasten in a single pass. In addition to metal, you can effectively fasten plywood, soft wood, composition board, drywall, insulation, and laminates to metal framing or components—opening up practical, time-saving options for contractors and DIY enthusiasts alike.

Built to endure demanding use, the Bit-Tip screws are made from strong, heat-treated steel and precision cold forged to ensure uniform dimensions and consistent drill-point contours. This thoughtful construction makes Bit-Tip an excellent replacement for rivets, nuts and bolts, spot welds, or adhesives, particularly in HVAC ducting, metal studs, and other structural or layered metal work. By reducing the need for separate drilling bits, taps, welding equipment, or extra fastening hardware, you can complete projects with fewer tools and less downtime.

Purpose-built for a modern toolbox, this screw set requires only a standard screw gun with drilling depth locator and up to 2500 RPM to perform. It’s a practical, reliable option when you need repeatable, professional-grade results without the overhead of additional equipment.
