Measuring 8 x 0.5 inches with 18 threads per inch (TPI), this screw features a No. 2 drill point that simultaneously drills a pilot hole and drives the fastener in a single operation. The shank is cold forged from heat-treated steel for consistent thread geometry and drill point contour. The 0.25-inch hex drive is compatible with standard bit holders and impact drivers. Sold in a bulk pack of 1000 units.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for residential and commercial HVAC duct assembly, sheet metal enclosures, equipment panels, and mechanical room fabrication. The bit-tip design produces an optimum hole size for tight thread engagement without a separate drill bit or pilot step. Its short 0.5-inch length makes it appropriate for thin-gauge steel joining where minimal penetration is required. HVAC installers, sheet metal workers, and mechanical contractors are the primary users of this fastener in both new construction and retrofit applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBit-tip point drills and fastens in one step, eliminating need for separate drill bits\u003c\/li\u003e\n  \u003cli\u003eCold forged construction ensures uniform thread dimensions and drill point contour\u003c\/li\u003e\n  \u003cli\u003eHeat-treated steel for added hardness and durability in metal-to-metal applications\u003c\/li\u003e\n  \u003cli\u003eHex washer head distributes clamping load and resists pull-through\u003c\/li\u003e\n  \u003cli\u003e0.25-inch hex drive is compatible with standard power drivers and bit holders\u003c\/li\u003e\n  \u003cli\u003eLifetime limited warranty per manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use fastener for light-gauge sheet metal applications typical in HVAC ductwork assembly and metal panel fabrication.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians and sheet metal workers using a power driver or impact driver with a 0.25-inch hex bit holder.
