Value Collection 0404FSR 4-40 Unc Thread Cutting Screw

Product Description

The VALUE COLLECTION 0404FSR is a 4-40 UNC thread cutting screw designed for creating threads in pre-drilled holes in metal, plastic, or composite materials. It features a round head with a combination slotted and Phillips drive, accepting a No. 1 driver bit. The screw measures 0.25 inches in length under the head and is manufactured from AISI 1016-1024 steel with a zinc-plated finish for corrosion resistance. A Type F point profile enables clean thread cutting without a tap. This fastener is installed by electricians, HVAC technicians, plumbers, and general trade professionals wherever a self-threading metal screw is required in light-gauge assemblies.

This screw is suited for light industrial and trade applications including electrical enclosures, HVAC sheet metal work, junction boxes, control panels, and equipment housings. The 4-40 UNC thread size is a common standard in small-fastener applications across residential and commercial equipment. The combination drive accepts both a flat-blade and a No. 1 Phillips screwdriver, making it versatile in the field. This SKU ships in a minimum order quantity of 100 pieces per order, making it appropriate for stocking or production use.

De-energize any electrical equipment before working inside enclosures or panels. Follow applicable NEC or equipment manufacturer guidelines when fastening within electrical or control assemblies.
