Overview
The AKM 338-Piece Thread Repair Kit delivers a comprehensive professional solution for repairing and replacing damaged or stripped internal screw threads across both SAE and metric specifications. This extensive all-in-one system eliminates the need for multiple specialized kits by providing complete coverage of the ten most common thread sizes used in automotive and industrial applications, making it an essential tool for mechanics, technicians, and maintenance professionals who work with diverse equipment standards.
Engineered to professional standards, this helicoil repair kit includes 338 precision-manufactured components spanning the complete thread repair workflow. The collection features high-speed steel drill bits for accurate hole preparation, thread taps for precise thread cutting, wire thread inserts for permanent restoration, installation tools for proper insert placement, and tang breaking tools for clean finishing. The kit covers metric sizes from M5 through M12 and SAE imperial sizes from 1/4 inch through 1/2 inch, providing versatility for domestic vehicles, import automobiles, machinery, and equipment manufactured to different international threading standards. Additionally, the included thread gauge enables accurate size identification and verification before beginning repairs.
The thread inserts in this kit create stronger internal threads than original materials, particularly beneficial when working with soft metals like aluminum commonly found in engine blocks and cylinder heads. Each insert is designed to distribute load more evenly across thread engagement, resulting in superior holding strength and resistance to vibration loosening. The system is specifically optimized for engine repair and automotive applications where thread integrity is critical for safety and performance, including spark plug installations, oil pan repairs, transmission housings, and critical fastener locations.
Organization and portability are emphasized through the custom carrying case that houses all 338 components in designated compartments. Each accessory has its dedicated storage location, with inserts packaged in separate boxes for easy size identification and inventory management. The systematic layout streamlines tool selection during repairs and protects components during transport between workshop locations, service bays, and job sites.
