Value Collection V93113PR 4 Round Head Sheet Metal Screw

Product Description

The VALUE COLLECTION V93113PR is a No. 4 round head sheet metal screw designed for light-duty fastening in sheet metal and thin-material applications. Manufactured from 18-8 stainless steel, it delivers solid corrosion resistance in both interior and exterior environments. The Type U drive point allows for self-piercing entry into pre-punched or drilled thin-gauge sheet metal without requiring a separate nut. At 3/16 inches length under head, this screw is suited for shallow-material stack-ups where fastener length must be controlled precisely. Installers in HVAC, electrical, and general trade work will find this size commonly used when securing panels, housings, and light sheet metal assemblies.

This screw sees regular use in HVAC ductwork panel assembly, electrical enclosure work, and general light sheet metal fabrication. The round head profile sits flush above the material surface and distributes clamping load across a wider bearing area than pan or flat head styles. The 18-8 stainless steel construction makes it appropriate for mildly corrosive environments and outdoor-exposed enclosures where standard steel fasteners would degrade. Sold in minimum order quantities of 1000 pieces per the supplier specification, this screw suits contractors and shops that maintain a working fastener inventory.

Key Features

• 18-8 stainless steel construction for corrosion resistance in indoor and outdoor applications
• No. 4 thread size with 3/16 inch length under head for shallow sheet metal work
• Round head profile provides a wider bearing surface than flat or pan head alternatives
• Type U point design enables self-piercing in thin pre-punched sheet metal
• Meets ASME B18.6.3 and ASME B18.6.4 dimensional standards
• Inch measurement system; length measured from under-head reference point

Compatibility

Designed as an OEM-style replacement or stock fastener for light-gauge sheet metal assemblies including HVAC panels, electrical enclosures, and general thin-metal fabrication where a No. 4 round head sheet metal screw is specified.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, or sheet metal fabricators using a manual or power screwdriver with the appropriate drive bit. De-energize all electrical enclosures and power down HVAC equipment before fastener work on live assemblies. Avoid over-torquing small-diameter screws in thin sheet metal, as stripping the material is a common failure point at this fastener size. Follow applicable local codes and manufacturer assembly specifications for fastener spacing and torque guidance.
