Value Collection 22514 Free Running Insert 3/8-16 10-pack

Product Description

The VALUE COLLECTION 22514 is a free running helical wire thread insert designed to restore or reinforce internal threads in metal components. Made from stainless steel with a bright, uncoated finish, this insert accepts a 3/8-16 UNC thread and measures 0.562 inches overall length, corresponding to a 1-1/2D length-to-diameter ratio. The tanged design allows for standard installation tooling and includes 7-1/4 free coils for consistent thread engagement. Machinists, maintenance technicians, and assembly professionals use this type of insert to bring damaged or worn threads back to full load-bearing specification without replacing the base component.

This insert is suited for general industrial and mechanical maintenance applications where 3/8-16 UNC thread repair or thread reinforcement is required. Typical installation environments include aluminum, cast iron, and other materials that benefit from a stronger, wear-resistant threaded interface. The stainless steel construction makes it a practical choice in moderate corrosion-exposure settings. The package contains 10 inserts, making it appropriate for service professionals who handle recurring thread repair tasks.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard inch-series fasteners
• 0.562 inches overall length at 1-1/2D ratio for balanced thread engagement
• 7-1/4 free coils provide consistent load distribution across the insert
• Tanged design compatible with standard helical insert installation tools
• Stainless steel construction with bright, uncoated finish for corrosion resistance
• Sold in a 10-pack to support professional repair volumes

Compatibility

Designed as a standard 3/8-16 UNC free running helical thread insert suitable for thread repair and reinforcement applications in a wide range of base materials.

Installation Notes

Installation requires a dedicated helical insert installation tool sized for 3/8-16 UNC threads; do not attempt to drive the insert with improvised tooling. Prepare the host bore using the correct tap size specified for helical inserts of this thread and length-to-diameter ratio, which differs from a standard 3/8-16 tap. After seating the insert, remove the driving tang using a tang break-off tool or punch. Power down and de-energize any machinery before performing thread repair work on installed components.
