Value Collection 386279 Wafer Head Sheet Metal Screw

Product Description

The VALUE COLLECTION 386279 is a Type A wafer head sheet metal screw designed for fastening thin-gauge metal in light-duty applications. It features a square drive recess, which provides positive bit engagement and reduces cam-out during installation. The screw is manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance. The wafer head profile sits low and distributes clamping load across a wide bearing surface, making it well suited for applications where a low-profile fastener is required. The 0.75-inch length is measured under the head. Electricians, HVAC techs, and general contractors routinely use this type of fastener when assembling sheet metal enclosures, ductwork components, and light structural panels.

This screw is appropriate for residential and light commercial applications involving thin sheet metal, metal framing, and similar materials. The Type A point is a self-tapping design that cuts its own thread path into pre-drilled or punched holes in sheet metal, eliminating the need for a separate tapping operation. The zinc finish provides basic protection against oxidation in dry interior environments. It is commonly used in HVAC duct assembly, electrical panel and enclosure fabrication, and general sheet metal work across multiple trades.

Key Features

• Wafer head profile provides a wide bearing surface and low-profile appearance at the fastener seat
• Square drive recess reduces cam-out and improves bit engagement during installation
• Type A self-tapping point cuts threads directly into sheet metal without a separate tapping step
• Grade 2 steel construction for adequate strength in light-duty sheet metal fastening
• Zinc finish offers basic corrosion resistance in dry indoor environments
• 0.75-inch length under head suits thin-gauge sheet metal panel and enclosure assembly

Compatibility

Designed for use in thin-gauge sheet metal applications including HVAC duct assemblies, electrical enclosures, and light metal framing where a Type A self-tapping wafer head fastener is specified.

Installation Notes

Installation is performed with a square-drive bit and a power or manual screwdriver. Pre-drill or use a punched pilot hole sized to the screw diameter for clean thread engagement with Type A point screws. Follow applicable trade codes and manufacturer guidelines when fastening electrical enclosures or duct assemblies. Avoid over-torquing, which can strip threads in thin-gauge material or deform the workpiece.
