Value Collection 0406FPF 4-40 Unc Thread Cutting Screw

Product Description

The VALUE COLLECTION 0406FPF is a 4-40 UNC thread cutting screw designed for creating mating threads in pre-drilled holes in thin metal, sheet metal assemblies, and similar substrates. This flat head screw measures 3/8 inches in overall length and features a Number 1 Phillips drive with a Type F point, which uses a blunt, interrupted thread design to cut cleanly without producing chips. Manufactured from AISI 1016-1024 steel and finished with a zinc plating for corrosion resistance, it meets ASME B18.6.3, ASME B18.6.4, and SAE J933 standards. Installers in electrical, HVAC, and light mechanical assembly applications rely on this fastener for secure, vibration-resistant connections in thin-gauge metal panels and enclosures.

This screw is suited for light-gauge metal assembly work in residential and commercial settings. Typical applications include fastening electrical panels, HVAC equipment covers, junction boxes, and sheet metal enclosures where a self-threading fastener eliminates the need for a tapped hole or separate nut. The flat head profile sits flush with the work surface after installation, making it appropriate for assemblies where a low-profile finish is required. This item is sold in minimum order quantities of 100 units per order.

Key Features

• 4-40 UNC thread size with Type F point cuts threads directly into pre-drilled holes in thin metal
• Flat head profile sits flush with the mating surface for a clean, low-profile finish
• Number 1 Phillips drive for compatibility with standard power and hand tools
• Zinc-plated AISI 1016-1024 steel construction provides corrosion resistance and mechanical strength
• Meets ASME B18.6.3, ASME B18.6.4, and SAE J933 dimensional and performance standards
• Minimum order quantity of 100 units makes this suitable for production and service stock

Compatibility

Designed as a standard 4-40 UNC thread cutting fastener for use in thin-gauge steel, sheet metal panels, and light-duty metal enclosures requiring a flush flat head profile.

Installation Notes

A licensed electrician, HVAC technician, or mechanical assembler typically installs thread cutting screws of this type. Always de-energize and lock out electrical enclosures or equipment before fastening or removing panel hardware. Use the correct pilot hole diameter for 4-40 UNC thread cutting applications per the fastener manufacturer or applicable standards. Avoid over-torquing, which can strip the cut threads in thin-gauge material.
