Meet Malco B134T Bit-Tip Drill and Tap Screws — the all-in-one fastening solution built for HVAC installations, structural and layered metal work. The 8-18 x 1" screws come in a convenient 500‑count tub and feature a 1/4" hex washer head for a secure drive in tight spaces.
Why Bit-Tip is different
- Drill-and-tap in one pass: Bit-Tip creates its own hole to the optimal size, delivering superior thread engagement and a tighter, more reliable hold without pre-drilling or tapping.
- Self drilling and self tapping: Designed to cut through metal and form threads as it seats, reducing assembly steps and the risk of misalignment.
- One-operation fastening: Aligns and fastens in a single motion, minimizing install time and eliminating common fit-up issues.
- Versatile performance: Engineered for structural and layered metal, including HVAC ductwork, metal framing, and sheet metal assemblies. Can also fasten plywood, soft wood, composition board, drywall, insulation, and laminates to metal framing or components.
- Durable construction: Precision cold-forged, heat-treated steel delivers uniform dimensions and dependable drilling points for consistent results across every screw in the tub.
- Tool-ready: Requires only a standard screw gun rated up to 2500 RPM with a depth locator—no specialized equipment needed.
Practical use cases and outcomes
- HVAC installations: secure duct supports, hangers, and fittings to metal studs or framing with a clean, vibration-resistant hold.
- Metal framing and structural work: quickly join components without rivets or bolts, reducing weight and improving workflow on busy jobsites.
- Layered metal assemblies: reliably fasten combinations of metal and wood or composite materials in one operation, keeping project timelines tight.
- Repairs and retrofits: replace multiple-step fastening methods with a single, dependable screw that drills, taps, and seats in place.
What sets this apart from alternatives
- Eliminates the need for separate drill bits, taps, rivets, spot welds, or adhesives—streamlining sourcing and reducing tool-changes on site.
- Offers precise thread engagement in a single action, improving hold strength in metal-thin or multi-layer assemblies.
- Uniform, repeatable results due to cold-forged fabrication, so every screw in the 500-tub performs consistently.
Ideal for professionals and skilled DIYers who value speed, reliability, and a cleaner finish on HVAC, metal fabrication, and retrofit projects. The Malco B134T Bit-Tip Drill and Tap Screws deliver a dependable, one-step fastening solution that simplifies assemblies, reduces tool requirements, and provides durable performance in structural and layered metal tasks.
