Value Collection 34780 Flat Head Phillips Sheet Metal Screw 50pk

Product Description

The VALUE COLLECTION 34780 is a No. 14 flat head Phillips sheet metal screw supplied in a 50-piece pack. It measures 1.5 inches in overall length and is manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The flat head profile sits flush with the work surface when driven fully, making it well suited for applications where a low-profile fastener is required. The Phillips drive allows use with standard power and manual drivers. Thread form is Type A and Type AB, covering both self-tapping into sheet metal and light-gauge materials. This fastener is a standard trade-supply item installed by HVAC technicians, electricians, plumbers, and sheet metal workers across residential and light commercial applications.

This screw is used wherever a flush-mount, self-tapping fastener is needed in sheet metal or light-gauge steel assemblies. Common applications include securing HVAC duct sections, electrical enclosures, junction box covers, equipment panels, and sheet metal brackets. The Type A and Type AB point types allow the fastener to pierce and tap its own threads without a pre-tapped hole in thin-gauge sheet metal. The 50-piece pack quantity suits single-job use or bench-stock replenishment for service vans and shop inventories.

Compatibility

Designed as a standard self-tapping sheet metal fastener suitable for HVAC ductwork, electrical enclosures, equipment panels, and general light-gauge sheet metal assemblies where a No. 14 flat head Phillips screw is specified.

Installation Notes

Installation is performed with a Phillips-head screwdriver or bit-tipped power driver set to an appropriate clutch setting to avoid overdriving the flat head. De-energize electrical equipment and shut down HVAC systems before fastening panels or enclosures in live installations. Pilot holes are not required for Type A and Type AB points in thin-gauge sheet metal, but a pilot hole may improve alignment in heavier-gauge stock. Avoid over-torquing, which can strip the self-tapped threads or crack thin sheet metal.
