Malco BT143G Bit-Tip Self-Drilling and Tapping Screws redefine fasten-in-one solutions for HVAC, structural metal, and layered metal assemblies. With a built-in drill point, these screws create their own pilot hole as you drive, delivering an optimal hole size for superior thread engagement and a tight, secure fit from the first turn.
One-pass fastening means fewer steps and dramatically less alignment trouble. The Bit-Tip design streamlines your workflow, letting you drill, tap, and fasten in a single operation. This is especially valuable on ductwork, metal framing, and panels where precision matters and time saves add up on every project.
Durable, consistently reliable performance comes from careful engineering. The BT143G screws are made from strong, heat-treated steel and precision cold-forged to ensure uniform dimensions and drill point contours. That translates to predictable results, less rework, and a more dependable hold in demanding HVAC and metal fabrications.
Key specifications: 5/16" hex washer head, #2 point, 10-16 thread, 3/4" overall length. These dimensions are chosen to deliver fast, clean engagements in structural and layered metal, with enough bite to secure materials without compromising material integrity.
What this screw can do for you:
- Eliminate separate drill bits, taps, rivets, nuts & bolts, or spot welds by drilling and threading in one motion.
- Secure metal components with a flush, low-profile washer head that helps distribute load and resist pull-out in HVAC assemblies.
- Attach a wide range of materials to metal framing or components, including plywood, softwood, composition board, drywall, insulation, and laminates—expanding your fastening options beyond metal-to-metal.
- Provide reliable, repeatable thread engagement for structural and layered metal applications, reducing the risk of misalignment and stripping.
Ideal use cases: HVAC duct installations, metal stud framing, panel mounting, electrical enclosures, duct supports, and other metal-to-metal or metal-to-wood assemblies where fast, accurate fastening is critical. The Bit-Tip approach shines in tight spaces where traditional drilling and tapping would slow you down or require multiple tools.
How to use: load the BT143G screw into a standard screw gun rated at up to 2500 RPM with a depth locator. Begin driving; the screw will drill its own pilot hole, tap threads as it advances, and seat with the washer head for a secure, clean finish. Follow manufacturer depth settings to avoid over-torquing while achieving strong clamping force.
This 100‑piece bag keeps your project on track without interruptions, giving you ready access to a proven, all-in-one fastening solution. The Malco BT143G Bit-Tip screws are a practical upgrade for pros who demand speed, consistency, and a reliable finish in HVAC and metalworking tasks.
