Value Collection SMPFI0-400620-100BX Sheet Metal Screw

Product Description

The VALUE COLLECTION SMPFI0-400620-100BX is a No. 4 flat head Phillips drive sheet metal screw designed for light-gauge metal fastening in HVAC, electrical, and general sheet metal fabrication work. Built from Grade 2 steel with a zinc finish for corrosion resistance, this screw measures 5/8 inches in overall length and uses a Type AB point for easy thread engagement in thin metal. Sold in a box of 100, it suits high-volume installation work where consistent fastener specs matter. Licensed tradespeople and sheet metal workers reach for this style screw for duct assembly, panel attachment, and electrical enclosure work.

This screw is appropriate for residential and light commercial applications involving thin-gauge sheet metal, including HVAC duct panels, junction box covers, metal framing components, and electrical enclosures. The flat head profile sits flush against the work surface, making it suitable where a low-profile fastener is required. The Phillips drive is compatible with standard power drivers and hand tools already on the truck or job site. The Type AB point cuts its own path into sheet metal without a pre-drilled pilot hole in most gauges.

Key Features

• No. 4 thread size with Type AB self-tapping point for direct metal engagement
• Flat head profile sits flush for low-profile installations
• Phillips drive compatible with standard power drivers and screwdrivers
• Grade 2 steel construction with zinc finish for corrosion resistance
• 5/8 inch overall length suits light-gauge sheet metal applications
• Box of 100 units supports production-volume fastening tasks

Compatibility

Designed as a general-purpose sheet metal fastener for use in light-gauge steel applications typical of HVAC ductwork, electrical enclosures, and metal panel assembly.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, or electricians depending on the application. Power down or de-energize any electrical enclosure before fastening covers or panels. Use a Phillips No. 2 bit for consistent drive engagement and to avoid cam-out. Do not overtighten in thin-gauge material, as the Type AB point can strip the sheet if torque is not controlled.
