Value Collection 31846 Hex Thread Cutting Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 31846 is a 3/8-16 UNC hex head thread cutting screw designed for fastening into materials that require the fastener to form or cut its own mating thread. Built from Grade 2 steel with a zinc-plated finish, this screw provides reliable corrosion resistance in typical indoor and light-duty applications. The Type F point features a blunt, tapered tip with cutting edges that remove material as the screw is driven, making it suitable for use in metal or other rigid substrates. The hex head design allows for wrench-driven installation with controlled torque. This fastener is a standard production and maintenance item used across mechanical, HVAC, plumbing, and electrical trade work.

The 31846 thread cutting screw is used in light fabrication, equipment assembly, and field repair work where a pre-tapped hole is not available or practical. The 3/8-16 UNC thread is a coarse Unified National thread standard, appropriate for general-purpose metal fastening. The 3/4-inch length under head suits shallow through-fastening applications in sheet metal brackets, enclosures, equipment panels, and similar assemblies encountered in HVAC, electrical, and plumbing installation work.

Key Features

• 3/8-16 UNC coarse thread for general-purpose metal fastening
• Type F point cuts its own thread in the mating material, eliminating need for a pre-tapped hole
• Hex head allows wrench-driven installation for consistent seating
• Grade 2 steel construction provides standard tensile strength for light-duty fastening
• Zinc-plated finish adds corrosion resistance for indoor and light-exposure environments

Compatibility

Designed as a standard 3/8-16 UNC thread cutting fastener suitable for use in metal panels, brackets, enclosures, and equipment assemblies where a Type F thread cutting screw of this thread size and length is specified.

Installation Notes

Installation is typically performed by mechanics, HVAC technicians, electricians, or plumbers during equipment assembly or field service. Ensure the mating material is appropriate for thread cutting and that the pilot hole diameter matches the recommended specification for 3/8-16 Type F screws. De-energize and lock out any equipment before fastening near electrical or mechanical components. Do not over-torque, as Grade 2 steel has lower proof load than higher-grade fasteners.
