ReSpec Thread Repair Tools

Restore and preserve original components instead of discarding them. ReSpec restores external threads without removing any material, ensuring they remain at full strength and are never weakened. For damaged internal threads on steering knuckle bores, the STEMCO RST-70I restores OEM-grade thread integrity without cutting, grinding, or removing material.

ReSpec is compatible with all thread types: metric, fine, coarse, and imperial. Available in different sizes to ensure precision and reliability for diameters from 3 mm to 1000 mm, one pitch size covers the full diameter range of the tool. These solutions are able to seamlessly adapt to many different sizes to give you more value in a single tool.

In certain cases, your required thread diameter or pitch may fall outside our standard range. We can custom-engineer a solution to address any internal or external threading challenge—regardless of diameter or pitch.

Independent testing by the Material Testing Institute Hannover (MPA) confirms that ReSpec-repaired threads withstand the same static and dynamic loads as new, undamaged threads—often with an even higher fatigue endurance limit.

During the rolling process, the thread surface is work-hardened—rather than being cut or removing materials — which increases durability and resistance to future wear.

Through an ongoing commitment to develop groundbreaking, innovative solutions, ReSpec is built with the highest quality materials, precision manufacturing, and rigorous quality assurance.
