Malco BT163G 12-14X3/4 Bit-Tip #3 Point Self-Tapping & Self-Drilling Sheet Metal Screws- 5/16" Hex Washer Head | HVAC Fastners | Structural & Layered Metal (100 Count)

Meet the Malco BT163G Bit-Tip self-tapping and self-drilling screw—a purpose-built fastener engineered to simplify metalwork across HVAC, structural, and layered metal projects. With a single-pass fastening capability, this screw creates its own hole, ensuring an optimal hole size for superior thread engagement and a tight, secure fit every time.

Why Bit-Tip matters

• One-pass fastening: Drills, taps, and screws in a single operation, eliminating alignment hassles and speeding up installations.
• Precision and consistency: Bit-Tip is precision cold-forged from high-quality steel and heat-treated for uniform dimensions and drill-point contours, delivering repeatable performance across jobs.
• Versatile applications: Beyond metal, this screw works with plywood, soft wood, composition board, drywall, insulation, and laminates—making it ideal for attaching non-metallic materials to metal framing or components.
• Eliminates extra tools: Bypass the need for separate drill bits, taps, rivets, spot welds, or adhesives—your standard screw gun is all you need (rated up to 2500 RPM with a drilling depth locator).

Key specifications and what they mean for you

The BT163G features a 12-14 thread size with a 3/4-inch length and a 5/16-inch hex washer head, driven by a Bit-Tip #3 point. This combination is tailored for sheet metal fastening where rapid hole creation and robust thread engagement matter most. The Bit-Tip geometry provides a clean start, reducing the risk of skive or misalignment and promoting dependable hold in structural and layered metal assemblies.

Ideal use cases

• HVAC installations where ductwork and metal framing must be bonded quickly and securely.
• Mounting insulation, laminates, or drywall to metal studs or framework without pre-drilling.
• Attaching plywood or softwood components to metal structures in fabrication or remodeling projects.
• Sheet metal fabrications that require precise hole formation and strong bite in a single toolpass.

How to use

1. Prepare your tool: use a standard screw gun rated up to 2500 RPM with a drilling depth locator installed.
2. Position the Bit-Tip screw at the desired point on metal or mixed-material assembly.
3. Drive the screw steadily; the Bit-Tip will create the hole, tap the threads, and fasten the components in one motion.
4. Verify seating and depth, adjusting the locator as needed for consistent results across multiple fasteners.

Who benefits

Ideal for HVAC technicians, metal fabricators, carpenters working with metal frames, and remodelers tackling projects that combine metal with wood, drywall, and composites. If you value faster installations, fewer steps, and reliable, uniform results, the Malco BT163G is a smart, difficult-to-match choice.

Bonus advantages

• Head design 5/16" hex washer provides a secure drive and flush finish in metal assemblies.
• Count and convenience is available in a 100-count box, ideal for crews and long-term projects.
• Durability you can feel: heat-treated steel and precision forging deliver dependable performance through repeated use on structural and layered metal builds.

With the Malco BT163G Bit-Tip screws, you gain a reliable, all-in-one fastening solution that reduces tool overhead, speeds up installations, and delivers strong, lasting joints in metal and mixed-material assemblies.
