Thread Repair Kit M12x1.75 – Complete Helicoil Insert System

Brief Overview

This M12x1.75 thread repair kit is a complete solution for restoring stripped or damaged threads in automotive engines, cylinder heads, and industrial equipment. Whether you're servicing high-mileage vehicles or performing maintenance on precision machinery, this kit delivers reliable, permanent thread restoration. It pairs well with smaller M10 insert systems for shops that service a range of engine sizes, and complements M12x1.5 kits for shops needing multiple pitch options on the same diameter.

Key Features & Components

This kit addresses the most common thread failure point in automotive and industrial work: stripped fastener holes in aluminum and cast iron. M12x1.75 fasteners appear in cylinder head bolt holes, intake manifold studs, thermostat housings, and industrial equipment mounting points. A single stripped hole that would otherwise require helicoil outsourcing or component replacement becomes a 15-minute in-house repair with this kit—transforming a cost center into a revenue generator.

Professional Recommendation

Stock this kit for shops servicing modern gasoline and diesel engines, particularly those handling rebuild work, high-mileage vehicles, or industrial maintenance. Pair it with complementary pitch options for complete M12 coverage, and train technicians on proper hole preparation to maximize insert integrity and customer satisfaction.
