Value Collection 31845 5/16-18 Unc Hex Thread Cutting Screw 50pk

Product Description

The VALUE COLLECTION 31845 is a 5/16-18 UNC hex head thread cutting screw designed for use in metal fastening applications where a self-threading connection is required. Built from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this screw features a Type F point, which cuts threads into pre-drilled holes in metal without requiring a tapped thread. The hex drive head allows installation with standard hex drivers or wrenches. Each package contains 50 screws, making it a practical stocking item for service vans, shop inventory, or job-site use. The 1 inch length under head suits a range of light- to medium-duty metal assembly tasks.

This screw is suited for trade applications involving sheet metal enclosures, HVAC equipment panels, electrical boxes, and similar light-gauge metal assemblies. The Type F thread cutting point is specifically designed for use in ferrous metals, making it a common choice when fastening steel brackets, mounting flanges, or equipment covers where pre-tapped holes are not present. Electricians, HVAC technicians, and general maintenance trades typically keep this size on hand for panel and enclosure work.

Key Features

• Type F point cuts threads directly into pre-drilled holes in ferrous metal — no tapping required
• 5/16-18 UNC thread for broad compatibility with standard hex fastener tooling
• Grade 2 steel construction provides reliable strength for light- to medium-duty metal assembly
• Zinc-plated finish offers basic protection against oxidation in dry indoor environments
• Hex head design accepts standard hex drivers, nut drivers, and wrenches for quick installation
• Sold in a 50-piece package to support stocking and repeat-use applications

Compatibility

Designed as an OEM-style replacement or stocking fastener for light-gauge ferrous metal assemblies requiring 5/16-18 UNC thread cutting screws with a Type F point.

Installation Notes

Installation should be performed by qualified tradespeople following applicable mechanical and electrical codes for the application. Ensure the pre-drilled pilot hole diameter is correctly sized for a 5/16-18 Type F thread cutting screw to avoid stripping or fastener failure. Apply appropriate torque using a calibrated hex driver or wrench — do not overdrive. In electrical enclosure applications, follow NEC guidelines for fastener use and panel integrity.
