    Alfa Tools TI66224K 3/8-16 Helical Thread Repair Kit

    Part #: AL-TI66224K

    The Alfa Tools TI66224K 3/8-16 Helical Thread Repair Kit is a complete, professional-grade solution for restoring stripped or damaged 3/8″-16 UNC threads and reinforcing new threads in soft or worn materials. Each kit includes precision-engineered stainless steel helical inserts, a correctly sized STI tap, installation tool, and tang break-off tool — everything required for fast, permanent thread repair. Built to ASME B18.29.1 and B1.1 standards, these free-running inserts deliver superior strength, vibration resistance, and corrosion resistance while maintaining standard thread dimensions. Ideal for automotive, aerospace, machinery, maintenance, and manufacturing applications, the TI66224K ensures durable, high-performance threads even in demanding, high-torque environments.
