Meet the Malco BT134 #2 Point 8-18 x 1" Bit-Tip Drill and Tap Screws — a purpose-built solution for fast, reliable fastening in HVAC, metal framing, and layered metal assemblies. Designed to simplify complex installs, these screws combine drilling and tapping in a single motion for consistent, repeatable results.

• Bit-Tip technology: drills its own hole to the optimum size, delivering superior thread engagement and a tight fit in a wide range of metal thicknesses. This means stronger joints with fewer cookied-out holes and less rework.
• One-step fastening: eliminates alignment challenges and reduces installation time. No separate pilot holes, taps, or rivets required.
• Self-drilling and self-tapping: versatility across structural and layered metal, plus compatibility with plywood, soft wood, composition board, drywall, insulation, and laminates when fastening to metal framing or components.
• 1/4" hex washer head: designed for smooth driving with standard screw guns and impact drivers, minimizing head stripping and providing solid load transfer.
• Durable construction: precision cold-forged, heat-treated steel for uniform dimensions, reliable drill-point contours, and long-lasting performance in demanding HVAC and metalwork environments.
• Bulk practicality: supplied in a high-volume carton — 8,000 screws per carton — ideal for contractor jobs, service fleets, and ongoing maintenance projects.

What makes BT134 stand out

Unlike traditional fasteners that require a pilot hole, taps, or separate welding steps, the BT134 family streamlines installation with a single, controlled operation. It’s the ideal choice for fast, code-compliant attachments where precision and speed matter—especially in HVAC ductwork, metal framing, and layered metal assemblies where exact hole size and thread engagement influence reliability and service life.

Designed for real-world use

Typical scenarios include securing metal panels to framing, attaching duct components, or fastening insulation and laminates to structural metal. The #2 point and 8-18 thread size are tuned for strong bite in common sheet-metal applications, while the 1" length accommodates moderate metal thicknesses without sacrificing thread engagement. The 1/4" hex washer head makes it easy to drive with standard tools you already own, without special adapters or accessories.

Tips for optimal results

• Use with a screw gun rated up to 2500 RPM and a depth locator to control insertion depth for consistent seating.
• Pair with compatible metal thicknesses to maximize thread engagement while avoiding over-penetration.
• Consider the BT134 as a robust replacement for rivets, nuts, bolts, spot welds, or adhesives in appropriate installations.
