Value Collection SMPFI0-400370-100BX Sheet Metal Screw

Product Description

The VALUE COLLECTION SMPFI0-400370-100BX is a No. 4 flat head Phillips sheet metal screw designed for light-duty fastening in metal fabrication, HVAC ductwork, electrical enclosures, and general sheet metal assembly. Each screw measures 3/8 inches in overall length and features a Type AB point for fast thread engagement in thin-gauge metal, sheet steel, and similar substrates. The zinc finish provides basic corrosion resistance for indoor and sheltered installations. Manufactured from Grade 2 steel, this screw delivers reliable clamping force for standard sheet metal applications. This package contains 100 screws sold as a single box quantity.

These screws are suited for residential and light commercial trade applications where a No. 4 fastener is required. HVAC installers commonly use this size for securing duct covers, access panels, and sheet metal assemblies. Electricians use flat head Phillips screws in panel boxes, conduit fittings, and enclosure work where a flush-seating fastener is needed. The flat head countersinks into pre-drilled or self-tapped holes, producing a low-profile finish that does not protrude above the material surface.

Key Features

• No. 4 thread size with 3/8 inch overall length for thin-gauge sheet metal fastening
• Type AB point for quick thread engagement without pre-tapping
• Flat head profile seats flush for a low-profile finish
• Phillips drive compatible with standard screwdrivers and power drivers
• Zinc finish for basic corrosion resistance in sheltered environments
• Grade 2 steel construction for consistent clamping strength

Compatibility

Designed as a standard No. 4 flat head Phillips sheet metal screw suitable for thin-gauge steel, aluminum sheet, and similar light-duty metal fastening applications common in HVAC, electrical, and general sheet metal work.

Installation Notes

Installation is performed by HVAC technicians, electricians, and sheet metal workers using a Phillips screwdriver or a power driver with the appropriate bit. Power down or de-energize any electrical enclosure before driving screws into live panels or boxes. Avoid over-torquing, which can strip the No. 4 thread in thin-gauge material or damage the Phillips recess. Pilot holes are recommended in harder substrates to prevent material distortion.
