With a #2 point and 3\/4\" length, plus a 1\/4\" hex washer head, these screws are built to shave seconds off each install while delivering a tight, secure hold.\u003c\/p\u003e \u003cp\u003eWhy Bit-Tip stands out: every BT133 drill-and-tap screw creates its own hole, resulting in the optimal hole size for superior thread engagement.

That means fewer call-backs and more consistent results across HVAC ductwork, metal framing, and structural assemblies.\u003c\/p\u003e \u003cp\u003eDesigned for structural and layered metal, these self-drilling and self-tapping sheet metal screws excel where traditional fasteners stumble. The Bit-Tip’s point length and geometry are tailored to penetrate metal thicknesses with confidence, while still accommodating other materials like plywood, softwood, composition board, drywall, insulation, and laminates that may need to bond to metal framing or components.\u003c\/p\u003e \u003ch3\u003eKey benefits you’ll notice on the job\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eOne-pass fastening\u003c\/strong\u003e with optimal hole size and thread engagement for a tighter, longer-lasting fit.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSelf-drilling and self-tapping\u003c\/strong\u003e eliminates the need for separate drill bits, taps, rivets, nuts, bolts, or welding.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCompatibility with standard tools\u003c\/strong\u003e requires only a screw gun rated up to 2500 RPM with a drilling depth locator.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVersatile material compatibility\u003c\/strong\u003e from metal to plywood, soft wood, drywall, insulation, and laminates bonded to metal framing.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDurable construction\u003c\/strong\u003e forged from heat-treated steel and precision cold-forged for uniform dimensions and consistent drill point contours.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBulk value\u003c\/strong\u003e sold in a 10,000-piece carton, ideal for contractors, HVAC installers, and shop floors requiring steady supply.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eThe BT133 is more than a screw—it's a complete fastening solution that simplifies installation, reduces equipment needs, and delivers dependable performance in HVAC fasteners, structural metal, and layered metal assemblies.
