Performance Tool Thread Repair Kit with Stainless Steel Inserts

The Performance Tool Thread Repair Kit with Stainless Steel Inserts line restores stripped or damaged threaded holes to their original size. Each kit works as a thread repair kit, thread insert kit, or rethreading kit. You can repair a hole and reuse the part, which avoids replacing a costly component such as a cylinder head, engine block, or transmission case.

Key Features:

• Restores original thread sizing: The inserts bring damaged holes back to their original thread size.
• HSS tap or reamer: Each kit includes a high-speed steel cutting tool to prepare clean, accurate threads for the insert.
• Stainless steel inserts: The inserts resist heat, rust, and corrosion, and give a durable replacement thread surface.
• Install/punch tool: The included tool seats and locks the insert in place.
• Multiple thread sizes: The line covers common standard (SAE) and metric sizes, plus a dedicated spark plug thread repair kit.

These kits suit automotive repair, engine and drivetrain maintenance, and general mechanical restoration in the home garage or professional shop. Performance Tool backs the line with a lifetime warranty.
