This AB Tools Thread Repair Kit is designed for professionals and DIY enthusiasts needing to restore damaged 3/8" x 16 UNC internal threads. Its primary benefit is creating a permanent, stronger thread in soft materials, preventing future wear and corrosion using durable stainless steel inserts. A minor caveat is that it specifically targets 3/8" x 16 UNC threads, requiring a different kit for other sizes. Key features include high-speed steel (HSS) tools, stainless steel helicoil inserts for maximum strength, and a comprehensive set of components for a complete repair process.

This kit is specifically designed for 3/8" x 16 UNC (Unified National Coarse) internal threads.
The kit is most effective on soft materials like aluminum, cast iron, and plastics where threads tend to strip easily. It can also be used on steel.
Yes, the kit includes 10 x 3/8" x 16 UNC inserts made of stainless steel for maximum strength and corrosion resistance.
The tang breaking tool is used to snap off the small lug (tang) at the bottom of the installed helicoil insert, ensuring a smooth, flush finish and preventing interference with the fastener.
The kit comes in a durable, blow-molded case designed for organized storage and easy transportation of all its components.
No, this specific kit is for the 3/8" x 16 UNC standard thread size. Metric thread repair requires a different kit.
The stainless steel inserts create a permanent repair that is typically stronger and more durable than the original threads in soft materials, resisting wear and corrosion.
Ensure the drill bit is sharp and properly seated in the drill chuck. Use appropriate speed and pressure for the material being drilled. Apply cutting fluid if necessary.
Ensure you are tapping straight and not cross-threading. Use a tap wrench for better control. Apply cutting fluid and back the tap out periodically to clear chips.
Verify that the threads tapped were correct for the insert size. Ensure no debris is present in the tapped hole. Make sure the insert is properly aligned on the installation tool.
Ensure the tang is fully seated within the tool. Apply firm, direct pressure. If the tang is not breaking, check for any obstructions or misalignment.
Compatibility: This kit is specifically designed for 3/8" x 16 UNC internal threads.
Setup and Use:
Care: Keep all components clean and dry. Store the kit in its original blow-molded case to protect the tools and prevent loss. Periodically inspect inserts for any signs of damage or corrosion, though the stainless steel construction offers significant protection.
