Value Collection HTCIF03100750US-100BX 5/16-18 Unc Screw

Product Description

The VALUE COLLECTION HTCIF03100750US-100BX is a 5/16-18 UNC thread cutting screw designed for creating mating threads directly in pre-drilled holes in metal materials without requiring a nut or pre-tapped thread. Built to Grade 2 steel with a zinc-plated finish, this hex head fastener features a Type F point for reliable thread cutting action in ferrous and light structural applications. The 3/4-inch length under head suits medium-depth fastening tasks where clean, self-threading engagement is required. Sold in a box of 100 units, this screw is a practical choice for production assembly, HVAC equipment installation, electrical enclosures, and general mechanical work.

This thread cutting screw is well-suited for light to medium-duty fastening in sheet metal, thin steel sections, and pre-drilled structural components. Common applications include securing panels, brackets, and housings in HVAC equipment, electrical cabinets, and plumbing support assemblies. The hex head drive allows for fast installation with a standard hex wrench or nut driver, making it efficient for repetitive assembly tasks in both shop and field environments. The zinc plating provides a base level of corrosion resistance suitable for indoor and sheltered installations.

Key Features

• 5/16-18 UNC thread size for compatibility with standard unified coarse thread applications
• Type F point cuts clean mating threads in pre-drilled holes without pre-tapping
• Hex head drive accepts standard hex wrenches and nut drivers for fast installation
• Grade 2 steel construction provides adequate tensile strength for light to medium fastening loads
• Zinc-plated finish delivers basic corrosion resistance for indoor and sheltered use
• Box of 100 units supports production assembly and stocking needs

Compatibility

Designed as a standard 5/16-18 UNC Type F thread cutting screw for use in pre-drilled holes in ferrous sheet metal and thin steel structural components typical of HVAC, electrical, and mechanical assembly applications.

Installation Notes

Installation is typically performed by mechanical assemblers, HVAC technicians, electricians, or plumbers during equipment assembly or bracket installation. Ensure the receiving material is pre-drilled to the correct pilot hole diameter as specified for 5/16-18 UNC thread cutting screws before driving. Use a calibrated torque driver or hex nut driver and avoid overtorquing, which can strip the formed threads in thin material. De-energize and lock out any equipment before fastening panels or covers on live electrical or mechanical systems.
