Malco BT131T #2 Point 8-18 x 1/2" | Bit-Tip Drill and Tap Screws | 1/4" Hex Washer Head | HVAC Fastners | Structural & Layered Metal | Self Tapping and Self Drilling Sheet Metal Screws, 1000 Pack

The Malco BT131T Bit-Tip self-drilling and tapping screws are engineered to drill their own hole, delivering the optimum hole size for superior thread engagement and a tighter, more durable fit in a single, streamlined operation. With Bit-Tip, alignment headaches disappear—one fastener, one hole, precise results every time. This BT131T model is built for reliability in HVAC work, structural and layered metal, and general sheet-metal fastening demands.

• One-pass fastening: The Bit-Tip design creates the pilot hole and threads the screw in one motion, reducing install time and eliminating misalignment between steps.
• Bit-Tip precision: The screw’s self-drilling and self-tapping point is crafted from heat-treated steel and cold-forged for uniform dimensions and consistent drill-point contours, ensuring predictable performance across jobs.
• Versatile applications: Ideal for HVAC fasteners, structural and layered metal assemblies, and fastening to various substrates. Plywood, soft wood, composition board, drywall, insulation, and laminates can be securely attached to metal framing or components using the same screw.
• Strong, reliable drive: The 1/4" hex washer head provides robust engagement with standard screw guns, while the #2 point and 8-18 x 1/2" size ensure effective penetration and load bearing in typical metal thicknesses.
• One screw to replace multiple methods: A practical alternative to rivets, nuts and bolts, spot welds, or adhesives. Bit-Tip can reduce the need for additional fastening equipment and tools.
• Practical, kit-ready solution: Available in a 1000-pack, ready for large-scale HVAC installations, industrial metal projects, or ongoing maintenance work.
• Simple setup: Requires only a standard screw gun rated up to 2500 RPM with a drilling depth locator—no separate drill bits, taps, or welding equipment needed.

Who benefits most: HVAC technicians, metal fabricators, facility maintenance teams, and DIY enthusiasts tackling metal framing or layered metal assemblies will appreciate the efficiency, consistency, and clean, single-step fastening that the Malco BT131T provides. Key benefits in practice: - You gain faster installations with fewer steps, reducing labor time on every project. - You achieve tighter thread engagement and a stronger hold by letting the bit-tipped screw create the correct hole size as it drives. - You simplify tool requirements: no separate drilling or tapping operations, just a single, straightforward fastening process. - You can confidently fasten into metal framing, while also attaching wood and other substrates to metal with one versatile fastener. Bottom line: If your projects involve HVAC ductwork, structural metal, or layered metal assemblies—and you value speed, precision, and fewer tools—you’ll appreciate the Malco BT131T Bit-Tip Screw’s capability to drill, tap, and fasten in one decisive step.
