Value Collection SMPFI0-400750-100BX No. 4 Sheet Metal Screw

Product Description

The VALUE COLLECTION SMPFI0-400750-100BX is a No. 4 flat head Phillips sheet metal screw designed for fastening thin metal panels, brackets, ductwork, and light-gauge sheet metal assemblies. The flat head profile sits flush with the surface after installation, making it suitable for applications where a low-profile finish is required. Manufactured from Grade 2 steel with a zinc finish for corrosion resistance, these screws measure 3/4 inches in overall length. They ship in a box of 100, making them a practical choice for contractors who need a reliable bulk supply on hand for day-to-day service work.

These screws are commonly used in HVAC ductwork assembly, electrical enclosure fabrication, sheet metal panel attachment, and light commercial or residential construction tasks. The Type A and Type AB point types allow the screw to self-start in pre-punched or pre-drilled holes in thin sheet metal without requiring a separate nut. The Phillips drive is compatible with standard Phillips No. 2 screwdrivers and power drivers, which are standard tools on most service trucks and job sites.

Compatibility

Designed as an OEM-style replacement or general-use fastener for light-gauge sheet metal applications typical in HVAC, electrical, and general sheet metal fabrication work.

Installation Notes

Sheet metal screws of this type are typically installed by HVAC technicians, electricians, or sheet metal workers using a No. 2 Phillips screwdriver or a power driver with the appropriate bit. Pre-punch or pre-drill the sheet metal to the correct pilot hole size for the No. 4 thread before driving to avoid stripping. Do not overtighten, as light-gauge sheet metal can deform or strip threads easily. Follow applicable local codes and manufacturer guidelines for fastener spacing and edge distance on ductwork or panel assemblies.
