Value Collection SMPPI0-400370-100BX Sheet Metal Screw 100

Product Description

The VALUE COLLECTION SMPPI0-400370-100BX is a No. 4 pan head sheet metal screw designed for fast, reliable fastening in light-gauge metal applications. It features a Phillips drive, a Type AB point for self-starting penetration without a pilot hole, and a zinc finish that provides corrosion resistance in typical indoor and light-exposure environments. The screw measures 3/8 inches in length under the head and is manufactured from Grade 2 steel. This box contains 100 screws, making it a practical quantity for production work, service calls, and field repairs.

Sheet metal screws of this size are commonly used in HVAC ductwork assembly, electrical enclosures, light-gauge metal brackets, and panel fastening. The No. 4 size and 3/8-inch length make this screw well suited for thin-material applications where a standard machine screw would not self-thread. HVAC technicians, electricians, and sheet metal workers routinely use screws of this type when fabricating or securing duct sections, junction boxes, and access panels.

Key Features

• Type AB point self-starts in light-gauge sheet metal without a pre-drilled pilot hole
• Pan head profile provides a wide bearing surface and low-profile seating
• Phillips drive compatible with standard No. 2 Phillips bits and screwdrivers
• Zinc finish resists corrosion in typical service environments
• Grade 2 steel construction balances strength and cost for high-volume fastening tasks
• Box of 100 supports production-volume work and minimizes restocking interruptions

Compatibility

Designed as a standard No. 4 by 3/8-inch pan head Phillips sheet metal screw for general use in light-gauge metal assemblies typical of HVAC, electrical, and sheet metal fabrication work.

Installation Notes

Sheet metal screws are installed by HVAC technicians, electricians, and sheet metal workers using a Phillips No. 2 bit in a hand screwdriver or power driver set to a controlled clutch torque to avoid stripping the material. De-energize any electrical panel or duct system before fastening near live components. Type AB screws are self-tapping in light-gauge steel but may require a pilot hole in heavier-gauge material. Follow applicable SMACNA, NEC, or local mechanical code guidelines for fastener spacing and quantity in duct and enclosure assemblies.
