The Malco BT153G 10-24 x 3/4 Bit-Tip #3 Point Self-Tapping & Self-Drilling Sheet Metal Screws deliver a one-step fastening solution for metal projects. With a 3/4″ bit length, 10-24 threads, and a 5/16″ hex washer head, these screws drill, tap, and fasten in a single motion for precise, secure connections in structural and layered metal assemblies.

• One-operation fastening= immediate hole creation, thread engagement, and secure seating without misalignment or multiple steps.
• optimum hole size= Bit-Tip design ensures the right hole every time, promoting robust thread engagement and a tighter, vibration-resistant fit.
• Self-drilling and self-tapping= eliminates the need for separate drill bits, taps, rivets, nuts and bolts, spot welds, or adhesives—streamlining your workflow.
• Versatile material compatibility= ideal for HVAC sheet metal and structural or layered metal, with added capability to fasten plywood, soft wood, composition board, drywall, insulation, and laminates to metal framing or components.
• Premium construction= precision cold-forged, heat-treated steel delivers consistent dimensions and drill-point contours for reliable performance across applications.
• Convenient head design= 5/16″ hex washer head provides strong seating and a clean, flush finish in metal assemblies.
• Fast installation with standard tools= works with a typical screw gun rated up to 2500 RPM and a drilling depth locator for controlled, repeatable results.
• Value-packed quantity= 100 screws per package, reducing reorders and keeping your toolbox stocked for ongoing metal fastening projects.

Who benefits from the Malco BT153G Bit-Tip Screws?

HVAC installers, metal fabricators, electricians, and DIY enthusiasts who frequently join metal panels, framing, and accessories will appreciate the predictable performance and time savings. When projects involve metal-to-metal joints or attaching non-metal substrates to metal framing, this Bit-Tip solution delivers reliable engagement and a clean, professional finish.

Why this approach stands out

Compared to traditional fasteners and multi-step processes, Bit-Tip screws simplify your toolkit: there’s no need to juggle drill bits, taps, rivets, welding equipment, or adhesives. The Bit-Tip approach reduces equipment requirements, speeds up job timelines, and minimizes error from misaligned holes or incomplete taps.

Practical tips for best results

• Set your depth locator to the correct drilling depth to avoid over-penetration or under-fastening.
• Start from a clearly marked point and maintain steady drill pressure to keep the bit-tip aligned with the pilot hole.
• Use on appropriate metal thickness for the Bit-Tip point length to maximize drilling and tapping performance.
• Pair with compatible HVAC or structural metal components for a secure, code-compliant installation.
