Value Collection SMPCI0-400500-100BX Sheet Metal Screw

Product Description

The VALUE COLLECTION SMPCI0-400500-100BX is a No. 4 pan head sheet metal screw with a combination slotted and Phillips drive. It measures 0.5 inches in length under the head and features a Type AB point for self-starting in sheet metal, light-gauge steel, and similar thin materials. Manufactured from Grade 2 steel with a zinc finish for corrosion resistance, this fastener is a standard choice for HVAC cabinet assembly, electrical enclosures, ductwork attachments, and general sheet metal fabrication. Sold in a box of 100 units.

This screw is suited for light-gauge sheet metal applications encountered in residential and commercial HVAC, electrical panel work, and equipment enclosure assembly. The Type AB point allows the screw to pierce and thread into pre-punched or self-drilled pilot holes without a separate tapping step. The pan head profile provides a broad bearing surface, keeping the fastener seated flush against thin metal panels and housing covers. Installers working on duct collars, access doors, and unit cabinet panels will find this size and drive combination widely applicable across common field tasks.

Key Features

• No. 4 thread size, 0.5-inch length under head — a compact size suited for thin-gauge sheet metal
• Combination slotted and Phillips drive — compatible with both flat-blade and Phillips screwdrivers or bits
• Type AB point — self-starting in pre-punched sheet metal without additional tapping
• Pan head profile — wide bearing surface keeps fastener seated against panel surfaces
• Grade 2 steel with zinc finish — standard corrosion resistance for interior sheet metal applications
• Box quantity of 100 — suitable for service stock, truck stock, or job-lot use

Compatibility

Designed as a general-purpose No. 4 Type AB pan head sheet metal screw for light-gauge steel applications including HVAC cabinet panels, electrical enclosures, ductwork accessories, and similar sheet metal assemblies requiring a 0.5-inch fastener length.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, electricians, and sheet metal workers using a Phillips or flat-blade bit driver. Power down and de-energize any equipment before fastening panels or enclosure covers. Use a pilot hole sized to the thread manufacturer recommendation for Type AB screws to avoid stripping thin-gauge material. Avoid over-driving — pan head screws seated in thin sheet metal can strip or deform the material if excessive torque is applied.
