Value Collection SMPFI0-400500-100BX Sheet Metal Screw

Product Description

The VALUE COLLECTION SMPFI0-400500-100BX is a No. 4 flat head Phillips sheet metal screw designed for light-gauge metal fastening applications. Built from Grade 2 steel with a zinc finish, it measures 0.5 inches in overall length and features a Type AB point for self-starting penetration into sheet metal without a pilot hole. Sold in a box of 100, these screws are a standard consumable for HVAC installers, electricians, and sheet metal workers who need reliable, corrosion-resistant fasteners for ductwork, panels, and enclosures.

These screws are suited for residential and light commercial applications where No. 4 fasteners are called for. Common uses include securing sheet metal duct sections, electrical enclosure panels, junction box covers, and HVAC equipment housings. The flat head profile sits flush with the material surface, making them appropriate where a low-profile finish is required. The Phillips drive is compatible with standard power screwdrivers and manual screwdrivers common on any trade job site.

Follow applicable NEC or IFGC guidelines when securing components in regulated assemblies.
