Stripped threads got you down? This CTA Tools Pro-Thread kit lets you repair damaged M5 x 0.8 threads quickly and permanently. It's perfect for fixing spark plug holes, engine parts, aluminum cases, or any metal or plastic where threads are worn out. The kit includes stainless steel wire inserts, a tap, and an installation tool. The process is simple: drill out the old thread with a 5.2mm (or 13/64\) drill bit, tap new threads, screw in the insert, then snap off the tang. The insert gives you a strong, wear-resistant thread that's often stronger than the original material. Great for automotive, motorcycle, small engine, or even household repairs. Saves you from replacing expensive components. Keep one in your toolbox—you'll be glad you did when a bolt hole strips out.
