Value Collection SMPFI-1203000-050B Sheet Metal Screw No. 12

Product Description

The VALUE COLLECTION SMPFI-1203000-050B is a No. 12 flat head Phillips sheet metal screw designed for fastening thin metal panels, brackets, ductwork, and sheet metal assemblies. Made from steel with a zinc finish for basic corrosion resistance, this screw measures 3 inches in length under the head and is driven with a No. 3 Phillips bit. It is manufactured to ASME B18.6.3 standards, making it a reliable choice for consistent dimensional tolerances. This package contains 50 screws. HVAC technicians, sheet metal workers, and general contractors commonly use this fastener in light commercial and residential applications.

This screw is suited for use in sheet metal fabrication, HVAC ductwork assembly, electrical enclosures, and general metal fastening tasks. The flat head profile sits flush with or countersinks into the workpiece surface, making it appropriate where a low-profile finish is required. The No. 3 Phillips drive is standard and works with common power drivers and hand tools found on any job site.

Compatibility

Designed as a standard No. 12 flat head Phillips sheet metal screw for use in residential and light commercial sheet metal, HVAC ductwork, electrical panels, and general metal fastening applications where ASME B18.6.3-compliant fasteners are required.

Installation Notes

Sheet metal screws are installed by qualified tradespeople including HVAC technicians, electricians, and sheet metal fabricators. Always drill a pilot hole of the appropriate diameter to prevent metal deformation and ensure proper thread engagement. Use a No. 3 Phillips bit and set the driver clutch to avoid stripping the drive recess. Follow applicable codes and manufacturer guidelines when fastening ductwork or electrical enclosures.
