Value Collection HWTCIF0310050US-100BX Hex Thread Cutting Screw

Product Description

The VALUE COLLECTION HWTCIF0310050US-100BX is a 5/16-18 UNC hex thread cutting screw designed for fastening into pre-drilled or punched holes in metal without requiring a pre-tapped thread. It features a hex washer head with a hex drive and a Type F point, which produces threads in the mating material as the screw is driven. Constructed from Grade 2 steel with a zinc-plated finish, this fastener provides basic corrosion resistance for light-duty indoor and protected-environment applications. The shank length under head measures 0.5 inches. HVAC, electrical, and general mechanical contractors use this screw type when attaching sheet metal components, brackets, and panels in fabrication or field assembly work.

This thread cutting screw is suited for light-gauge metal fastening tasks commonly encountered in HVAC sheet metal work, electrical enclosure assembly, and general mechanical fabrication. The Type F point cuts its own thread path on installation, eliminating the need for a pre-tapped hole and speeding up assembly on production or service work. The hex washer head provides a bearing surface that distributes clamping load and resists pull-through in thinner gauge materials. This item is sold with a minimum order quantity of 10 pieces.

Key Features

• Type F point cuts threads on installation — no pre-tapped hole required
• Hex washer head distributes clamping load and resists pull-through
• Hex drive compatible with standard hex bit or socket drivers
• Grade 2 steel construction for light-duty structural fastening
• Zinc-plated finish provides basic corrosion protection in dry or indoor environments
• 5/16-18 UNC thread size with 0.5 inch length under head for shallow-depth fastening applications

Compatibility

Designed as a standard Type F hex washer head thread cutting fastener for use in light-gauge steel, sheet metal panels, brackets, and enclosures where a self-threading screw with a 5/16-18 UNC thread form is specified.

Installation Notes

Installation is performed with a hex bit driver or socket wrench sized for the hex washer head drive. Ensure the receiving material gauge is appropriate for the 5/16-18 thread to cut and hold adequately — verify against the fastener manufacturer's recommended material thickness range before driving. Power down or de-energize any electrical enclosure or HVAC unit before driving fasteners into its panels. Do not overtorque; thread cutting screws in light-gauge metal can strip the formed thread if driven past seating.
