Value Collection HTCIF03101500US-100BX 5/16-18 Hex Screw

Product Description

The VALUE COLLECTION HTCIF03101500US-100BX is a 5/16-18 UNC hex head thread cutting screw with a Type F point, designed for creating threads in pre-drilled holes in metal and other hard materials. Made from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this screw measures 1-1/2 inches in length under head. The hex drive allows for high-torque installation with a standard hex socket or wrench. This box contains 100 screws, making it suitable for production assembly, sheet metal fabrication, and general mechanical fastening tasks performed by electricians, HVAC technicians, plumbers, and other tradespeople.

This screw is suited for applications where a self-threading fastener is needed in ferrous or non-ferrous metals, plastics, and similar materials. The Type F point features cutting flutes that remove material as the screw is driven, creating clean, accurate threads without a tap. Typical use cases include securing sheet metal panels, electrical enclosures, HVAC equipment housings, and mechanical assemblies where a permanent threaded connection is required. The zinc plating provides a functional level of protection in standard indoor and light-duty service environments.

Key Features

• 5/16-18 UNC thread size for compatibility with standard inch-series tapped holes and pre-drilled sheet metal
• Type F point with cutting flutes threads directly into pre-drilled holes without a tap
• Hex head and hex drive accept standard hex sockets and wrenches for high-torque installation
• Grade 2 steel construction provides adequate tensile strength for light to medium fastening loads
• Zinc-plated finish resists corrosion in indoor and low-moisture environments
• Sold in a box of 100 screws for production and service use

Compatibility

Designed as a standard UNC thread cutting fastener for use in pre-drilled metal, thermoplastics, and composite materials requiring a Type F self-threading screw in the 5/16-18 thread size.

Installation Notes

Installation is performed using a hex socket driver or open-end wrench sized to the hex head. Ensure the pre-drilled pilot hole diameter matches the recommended specification for a 5/16-18 Type F thread cutting screw to avoid stripping or thread damage. De-energize and lock out any electrical or mechanical systems before fastening into live equipment enclosures, per NFPA 70E and applicable local codes. Do not over-torque, as Grade 2 steel has lower yield strength than higher-grade fasteners.
