Value Collection SPTCIF02500370-100BX Thread Cutting Screw

Product Description

The VALUE COLLECTION SPTCIF02500370-100BX is a 1/4-20 UNC thread cutting screw with a 3/8-inch length under head, designed for creating mating threads in pre-drilled holes in thin metal, sheet stock, and similar substrates. The pan head profile provides a low-profile bearing surface, and the slotted drive accepts a standard flat-blade screwdriver. Constructed from Grade 2 steel with a zinc-plated finish, this screw resists light corrosion in typical interior applications. The Type F point features a blunt, chamfered tip with cutting edges that tap threads as the screw is driven, eliminating the need for a separate tapping operation. Sold in a box of 100.

This screw is suited for light-gauge metal assembly work encountered in HVAC ductwork, electrical enclosures, sheet metal panels, and similar trade applications. The 1/4-20 UNC thread standard is widely used in mechanical and electrical assembly, making this fastener a practical stock item for service vans and shop use. The zinc plating provides adequate corrosion protection for dry indoor environments. Pack quantity of 100 supports bulk installation jobs where consistent fastener performance is required across multiple connection points.

Key Features

• Grade 2 steel construction with zinc-plated finish for light corrosion resistance
• Sold in a 100-count box for bulk job site or shop use

Compatibility

Designed as a standard 1/4-20 UNC Type F thread cutting screw suitable for light-gauge metal substrates where a self-tapping fastener with a pan head and slotted drive is specified.

Installation Notes

Thread cutting screws require a properly sized pilot hole in the mating material before installation — using an undersized or absent pilot hole can strip threads or damage the workpiece. Drive with a flat-blade screwdriver or appropriate bit, and avoid overdriving, which can strip the newly cut threads. Power down or de-energize any electrical enclosure or HVAC unit before fastening panels or covers. Follow applicable codes such as NEC or SMACNA guidelines when securing electrical or sheet metal assemblies.
