Sized at No. 8 x 2-1\/2 inches, these screws feature a zinc coating for corrosion resistance in typical indoor and light-duty applications. The hex washer head design allows for driver engagement with a standard hex bit or nut driver, providing consistent torque and a built-in washer bearing surface that distributes clamping load and reduces pull-through. These fasteners are commonly installed by HVAC technicians, sheet metal workers, plumbers, and general contractors working with light-gauge metal components.\u003c\/p\u003e\n\u003cp\u003eType A sheet metal screws are intended for use in light-gauge sheet metal, thin metal panels, and similar substrates where a self-tapping thread form is appropriate. The 2-1\/2-inch length provides adequate thread engagement for multi-layer assemblies or thicker material stacks. The hex washer head style is a standard choice for ductwork, equipment enclosures, access panels, and general sheet metal fabrication in residential and light commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType A self-tapping thread form for use in light-gauge sheet metal and thin metal substrates\u003c\/li\u003e\n  \u003cli\u003eNo. 8 x 2-1\/2 inch size for thread engagement in multi-layer or thicker material assemblies\u003c\/li\u003e\n  \u003cli\u003eHex washer head allows driving with a standard hex bit or nut driver\u003c\/li\u003e\n  \u003cli\u003eIntegrated washer bearing surface distributes clamping load and reduces pull-through risk\u003c\/li\u003e\n  \u003cli\u003eZinc coating provides corrosion resistance for typical indoor service environments\u003c\/li\u003e\n  \u003cli\u003eSold as a jar of 100 screws for convenient jobsite storage and dispensing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type A hex washer head sheet metal screw suitable for light-gauge metal fabrication, ductwork assembly, equipment enclosures, and general sheet metal fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by sheet metal workers, HVAC technicians, and general contractors using a hex bit driver or nut driver sized to the head.
