Value Collection SMPPI0-400750-100BX Sheet Metal Screw

Product Description

The VALUE COLLECTION SMPPI0-400750-100BX is a No. 4 pan head sheet metal screw designed for fastening thin-gauge metal panels, ductwork, and light sheet metal assemblies. Manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance, this screw features a Type AB point for fast thread engagement without pre-drilling in light-gauge materials. The 3/4-inch length is measured under the head. Supplied in a box of 100, these screws are a standard consumable on HVAC duct installations, electrical enclosure work, and general sheet metal fabrication. Phillips drive allows use with common powered drivers and hand screwdrivers.

These screws are suited for residential and commercial applications where No. 4 fasteners are specified. Typical uses include securing sheet metal duct sections, junction box knockouts, light-gauge brackets, and metal roofing accessories. The pan head profile distributes clamping load across a wider surface area than a flat head, reducing pull-through risk in thin substrates. The zinc finish provides a baseline level of corrosion protection appropriate for dry interior environments. Sold in minimum quantities of 100 per order, making them practical for stocking a service van or shop supply.

Key Features

• No. 4 thread size with Type AB point for self-starting in light-gauge sheet metal without pre-drilling
• 3/4-inch length under head for consistent depth engagement in thin material stacks
• Pan head profile provides broad bearing surface to minimize pull-through
• Phillips drive compatible with standard powered and manual drivers
• Grade 2 steel construction with zinc finish for basic corrosion resistance in dry environments
• Box of 100 for efficient jobsite and shop stocking

Compatibility

Designed as a standard No. 4 pan head Phillips sheet metal screw suitable for light-gauge steel sheet metal applications including HVAC ductwork, electrical enclosures, and general metal fabrication where a Type AB point fastener is specified.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, electricians, and sheet metal workers using a Phillips-tip powered driver or hand screwdriver. Ensure the mating material is properly clamped or fixtured before driving to prevent sheet walking. Type AB point screws do not require a pilot hole in light-gauge material, but a pilot hole may improve alignment in thicker stock. Wear appropriate PPE when working with sheet metal edges.
