Value Collection HTCIF03101000US-100BX Thread Cutting Screw

Product Description

The VALUE COLLECTION HTCIF03101000US-100BX is a 5/16-18 UNC hex head thread cutting screw designed for creating mating threads in pre-drilled or punched holes in metal and other hard materials. Built from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this screw features a Type F point that cuts rather than displaces material, producing clean, secure threads on first drive. The hex head accepts a standard hex socket or wrench for high-torque driving. At 1 inch of length under head, this fastener is suited for light- to medium-duty structural and mechanical assembly work. The package quantity is 1 unit with a minimum order quantity of 10.

This thread cutting screw is commonly used in HVAC equipment assembly, electrical panel fabrication, sheet metal ductwork, and general mechanical applications where a tapped hole is not practical or available. The Type F point is appropriate for use in steel, aluminum, and other metals within the thickness range suited for 5/16-18 UNC fasteners. Installers in HVAC, plumbing, and light manufacturing settings rely on this screw size for securing brackets, panels, and structural components during installation and service work.

Key Features

• Type F point cuts clean mating threads without a pre-tapped hole
• 5/16-18 UNC thread form for compatibility with standard inch-series applications
• Hex head design allows high-torque driving with a socket wrench or hex bit
• Grade 2 steel construction provides reliable strength for light- to medium-duty fastening
• Zinc-plated finish offers basic protection against corrosion in dry indoor environments
• 1 inch length under head suits typical sheet metal and bracket assemblies

Compatibility

Designed as a standard 5/16-18 UNC thread cutting screw suitable for use in metal fabrication, HVAC equipment, and general mechanical assemblies requiring a self-threading hex head fastener.

Installation Notes

This screw is installed by trade mechanics and HVAC technicians using a hex socket, nut driver, or wrench sized for a 5/16-inch hex head. Ensure the receiving material is pre-drilled to the correct pilot hole diameter for 5/16-18 UNC thread cutting applications before driving. De-energize any electrical equipment and shut off system power before fastening components inside live panels or mechanical enclosures. Do not overdrive, as stripping the cut threads in thin-gauge metal will compromise joint integrity.
