Malco BT164G 12-14X1 Bit-Tip #3 Point Self-Tapping & Self-Drilling Sheet Metal Screws- 5/16" Hex Washer Head | HVAC Fastners | Structural & Layered Metal (Count)

Experience a smarter, faster fastening solution with the Malco BT164G 12-14X1 Bit-Tip #3 Point Self-Tapping & Self-Drilling Sheet Metal Screws. Designed specifically for HVAC fasteners and structural or layered metal, these screws combine drilling, tapping, and securing into one precise action.

One-pass fastening for precise, repeatable results

Bit-Tip creates its own hole, delivering the optimum hole size for superior thread engagement and a tight, vibration-resistant fit. That means fewer misalignments, less rework, and a cleaner finished assembly. With a single operation, you can drill, tap, and fasten—even in challenging metal thicknesses—without juggling separate drill bits or taps.

Why this Bit-Tip matters

• Self-drilling and self-tapping action: Eliminates the need for pre-drilling and separate tapping, speeding up installations and reducing tool changes.
• #3 point geometry paired with a 12-14X1 Bit-Tip profile provides robust performance across metal thicknesses commonly found in HVAC framerwork and structural panels.
• 5/16" Hex Washer Head delivers strong seating, flush finish, and low pull-through in sheet metal assemblies.
• Premium steel construction: Cold-forged, heat-treated steel ensures uniform dimensions and durable drill-point contours for consistent results job after job.
• eliminates costly auxiliary tooling: Replaces rivets, nuts and bolts, spot welds, or adhesives in many fastening tasks and removes the need for additional drilling or welding equipment.
• Depth control ready: Compatible with a standard screw gun up to 2500 RPM and a drilling depth locator to prevent over-penetration.

Versatile applications for HVAC, structural, and layered metal

These screws excel in metal-to-metal assemblies as well as attaching materials to metal framing. Use cases include HVAC duct support, metal studs and channels, and fastenings across layered metal assemblies. The Bit-Tip is also effective when you need to join plywood, softwood, composition board, drywall, insulation, or laminates to metal framing or components, broadening the scope of projects you can tackle with a single fastener.

What makes Malco BT164G unique

• Bit-Tip design delivers the optimum hole size for better thread engagement and a tighter, more secure fit than traditional fasteners.
• One-operation fastening reduces alignment issues and installation time, especially in tight or awkward spaces.
• Precision cold forging and heat treatment yield consistent dimensions and drill-point contours across production lots.
• Known as an excellent replacement for rivets, nuts and bolts, spot welds, or adhesives in many applications—streamlining inventories and repair workflows.

Pro tips for best results

• Choose Bit-Tip size and point geometry based on the target metal thickness and desired clamp load. The point length determines how thick a material can be drilled, tapped, and fastened in one go.
• Use a screw gun with a depth locator and set the RPM limit close to 2500 to optimize the self-drilling action without overdriving.
• When fastening to layered assemblies, start with a pilot mental plan for the order of operations to maintain alignment and achieve a clean finish.

In short, the Malco BT164G 12-14X1 Bit-Tip #3 Point Self-Tapping & Self-Drilling Sheet Metal Screws redefine everyday metal fastening—combining drilling, tapping, and fastening into a single, reliable operation. Built for HVAC professionals, fabricators, and contractors working with structural and layered metal, this screw delivers consistent performance, reduces tool clutter, and accelerates project timelines.
