Value Collection 0408FPF 4-40 Unc Thread Cutting Screw

Product Description

The VALUE COLLECTION 0408FPF is a 4-40 UNC thread cutting screw designed for creating mating threads in pre-drilled holes in metal or plastic substrates. Built from AISI 1016-1024 steel with a zinc-plated finish, it resists corrosion in typical indoor service environments. The flat head profile sits flush with the mating surface, and the Type F point — a blunt, chip-clearing design — cuts clean threads without a tap. A No. 1 Phillips drive keeps installation straightforward with standard tooling. Overall length is 0.5 inches. This screw is sold in minimum quantities of 100 units per order.

Thread cutting screws like the 0408FPF are commonly used in light sheet metal assemblies, electrical enclosures, HVAC equipment panels, and control box fabrication. The 4-40 UNC thread is a fine-pitch unified coarse designation frequently specified in instrumentation, small appliance, and control hardware applications where a secure, vibration-resistant fastened joint is needed in thin-gauge material. Installation is performed by electricians, HVAC technicians, and sheet metal workers during equipment assembly or field repair work.

Key Features

• Type F point cuts threads on installation — no pre-tapping required
• Flat head design sits flush with the work surface
• No. 1 Phillips drive for standard screwdriver or bit compatibility
• AISI 1016-1024 steel construction meets ASME B18.6.3, ASME B18.6.4, and SAE J933 standards
• Zinc-plated finish provides corrosion resistance in indoor applications
• 4-40 UNC thread suits thin-gauge metal panels and enclosures

Compatibility

Designed as an OEM-style replacement or standard fastener for use in thin-gauge metal or plastic assemblies requiring a 4-40 UNC thread cutting screw with a flat head and Type F point.

Installation Notes

Install with a No. 1 Phillips screwdriver or power bit driver set to a low-torque clutch setting to avoid stripping the driven head or over-threading the mating material. Ensure the receiving hole diameter matches the recommended clearance for a 4-40 Type F thread cutting screw per ASME B18.6.4 to achieve proper thread engagement. De-energize any electrical panel or enclosure before fastener work in live equipment per applicable NEC requirements.
