Value Collection HTCIF03100620US-100BX Thread Cutting Screw

Product Description

The VALUE COLLECTION HTCIF03100620US-100BX is a 5/16-18 UNC thread cutting screw designed for creating mating threads in pre-drilled holes without the need for a tapped thread. The screw measures 0.625 inches in length under the head and features a hex drive head for high torque application with a standard hex wrench or socket driver. Constructed from Grade 2 steel with a zinc-plated finish, this fastener provides corrosion resistance suitable for general-purpose indoor and light-duty applications. The Type F point features a blunt, tapered end with cutting edges that remove material as the screw is driven, making it well suited for use in metal substrates. This box contains 100 screws.

This thread cutting screw is used across HVAC, sheet metal, electrical enclosure, and light structural assembly work where a reliable machine-thread engagement is needed in metal. The 5/16-18 UNC thread profile is a coarse unified national thread, commonly used in steel panels, brackets, junction boxes, and equipment frames. Installers in HVAC, electrical, and mechanical trades reach for Type F thread cutting screws when attaching components to pre-punched or drilled metal where self-tapping thread formation is required. The hex head allows high seating torque and easy removal in service applications.

• Sold in a box of 100 screws for trade and production quantities

Compatibility

Designed for use in pre-drilled or punched metal substrates requiring a 5/16-18 UNC thread cutting fastener. Typical applications include steel panels, enclosures, brackets, and mechanical equipment frames in HVAC, electrical, and general mechanical assembly.

Installation Notes

Installation is performed with a hex wrench, hex bit driver, or socket rated for the fastener size. Ensure the pilot hole diameter is matched to the manufacturer recommendation for 5/16-18 Type F thread cutting screws in the specific substrate material and thickness. Do not exceed the rated drive torque for the screw grade to avoid stripping the newly formed threads. Follow applicable codes such as the NEC or IFGC for fastener requirements in regulated system assemblies.
