Value Collection SMPPI0-400500-100BX Sheet Metal Screw 100pk

Product Description

The VALUE COLLECTION SMPPI0-400500-100BX is a No. 4 pan head sheet metal screw designed for secure fastening in light-gauge metal applications. It features a Phillips drive, a Type AB point for self-starting entry into pre-drilled or punched sheet metal, and a zinc finish that provides basic corrosion resistance. The screw measures 0.5 inches in length under the head and is manufactured from Grade 2 steel. These fasteners are sold in boxes of 100 and are a standard consumable for HVAC, electrical, and sheet metal fabrication work.

These screws are commonly used in residential and light commercial settings wherever light-gauge sheet metal panels, ductwork covers, electrical enclosures, and junction box knockouts need to be secured. The pan head profile provides a low-profile bearing surface that resists pull-through on thin metal substrates. The Type AB thread form cuts into material on initial installation without requiring a pre-tapped hole, making it well suited for fast field assembly and cabinet work.

Key Features

• No. 4 thread size with Type AB self-starting point for use in sheet metal
• Pan head profile distributes clamping load over a broad surface area
• Phillips drive compatible with standard power and hand drivers
• Zinc finish provides basic corrosion resistance for indoor applications
• Grade 2 steel construction meets standard mechanical property requirements
• Sold in boxes of 100 for jobsite and shop restocking convenience

Compatibility

Designed as a standard No. 4 pan head Phillips sheet metal screw suitable for light-gauge steel panels, ductwork, electrical enclosures, and similar thin-metal fastening applications.

Installation Notes

Install with a Phillips screwdriver or power driver set to a controlled torque clutch setting to avoid stripping the drive recess in light-gauge material. Sheet metal workers, HVAC technicians, and electricians routinely use these fasteners during panel assembly and enclosure work. Ensure the substrate is properly supported before driving to prevent deformation of thin metal. Follow applicable codes, including NEC requirements for electrical enclosure fastening where relevant.
