Malco BT132G #2 Point 8-18 x 5/8" | Bit-Tip Drill and Tap Screws | 1/4" Hex Washer Head | HVAC Fastners | Structural & Layered Metal | Self Tapping and Self Drilling Sheet Metal Screws, 100 Bag

Meet Malco BT132G, the Bit-Tip self-drilling and self-tapping screw engineered for fast, precise fastening in HVAC, sheet metal, and structural applications. Designed to drill its own pilot hole to the optimum size, it delivers better thread engagement and a tighter fit in a single operation—eliminating misalignment and saving you time on every install.

Where Bit-Tip truly shines is in its versatility and reliability. The #2 point and 8-18 thread work together with a 5/8" length to handle common metal thicknesses found in structural and layered metal assemblies, ductwork, and metal framing. The 1/4" hex washer head accepts standard screw guns and depth locators, enabling controlled, consistent seating without guesswork.

• One-pass fastening: drills, taps, and fastens in a single motion, dramatically reducing installation time and potential alignment issues.
• Optimum hole size every time: Bit-Tip’s point geometry and precision cold forging ensure uniform drill point contours and reliable thread engagement across a range of materials.
• Wide material compatibility: ideal for structural and layered metal; also suitable for attaching plywood, softwood, composition board, drywall, insulation, and laminates to metal framing or components.
• Durable construction: made from heat-treated steel for high strength and long service life, ready to stand up to demanding HVAC and metalwork environments.
• Concrete replacement for common fasteners: a practical alternative to rivets, nuts and bolts, spot welds, or adhesives—streamlining tooling needs and cutting equipment costs.
• Packaging you can count on: 100 screws per bag, ready for job-site use without frequent reordering.

Why this Bit-Tip matters for HVAC and metalwork

HVAC installers and metal fabricators value speed, accuracy, and minimal equipment. The BT132G delivers all three by removing the extra steps of pilot drilling, tapping, and separate fastener sets. It’s particularly effective for attaching duct hangers, metal studs, vapor barriers, or insulation to metal frames where space is tight and precision matters. And because it bonds to multiple substrates without pre-drilling, it reduces vibration and pull-out risk in dynamic environments.

Practical tips for best results

• Use a screw gun rated around 2500 RPM with a depth locator to prevent over-penetration and ensure consistent seating.
• Match the screw length (5/8") to your target metal thickness to avoid excess protrusion.
• Test a sample hole on a scrap piece of the same material to confirm bite and thread engagement before the full run.
• For multi-layer assemblies, start with Bit-Tip in the top layer; the self-drilling action will guide the screw through subsequent layers smoothly.

In short, Malco BT132G Bit-Tip screws aren’t just fasteners—they’re a streamlined fastening solution that reduces tool requirements, speeds HVAC and metal projects, and delivers dependable performance across metal, wood, and composite materials. If you’re tackling structural and layered metal work where quick, accurate, and repeatable fastening matters, this 100‑piece bag of 8-18 x 5/8" Bit-Tip screws is precisely what your toolkit needs.
