The GENERIC / UNBRANDED fpsd634 is a No. 6 x 0.75 inch flat-head Tek sheet metal screw sold in a 100-pack. Tek-style screws feature a self-drilling tip that eliminates the need for a separate pilot hole, making them a standard fastener choice for light-gauge sheet metal work. These screws are commonly used in HVAC duct fabrication, electrical panel enclosures, and general sheet metal assembly. The flat-head profile sits flush with the surface after installation, which is important in applications where clearance is limited or airflow must not be obstructed.
These fasteners are suited for residential and light commercial HVAC work, including duct board assembly, sheet metal duct connections, equipment enclosures, and similar trade applications. The 100-pack quantity is appropriate for service technicians and installers who need a reliable bulk supply on the job site or in a service van stock.
Designed for use with light-gauge sheet metal assemblies typical in HVAC ductwork fabrication, equipment enclosures, and related trade applications.
Sheet metal screws are installed by HVAC technicians, electricians, and general sheet metal workers using a power drill or screw gun with the appropriate bit. Ensure the mating material is within the rated gauge range for the self-drilling tip before driving. Do not overtorque, as the threads in thin sheet metal can strip if excessive force is applied.
