Thread repair kit GEKO M5–M12, 131 pieces, for restoring damaged internal and external threads

The GEKO thread repair kit M5–M12, 131 pieces, is a comprehensive set designed to restore damaged internal and external metric threads from M5 to M12. The kit includes a selection of taps, dies, thread inserts and accessories that allow technicians and maintenance personnel to recondition worn or damaged threads to functional condition. It is intended for workshop and field use on machinery, automotive components and general equipment where restoring original thread fit and function is required.

Advantages

How to use

Select the appropriate tool for the damaged thread size and secure the workpiece. For internal threads, use the matching tap to cut or chase the damaged thread, then fit the appropriate thread insert according to its installation procedure to restore thread form and strength. For external threads, use the matching die to re-cut the thread on bolts or studs. Follow correct alignment, cutting speed and lubrication guidance for clean, concentric threads. Inspect the repaired thread for proper fit with mating parts and, when required, apply thread locker or torque to specification during reassembly.

Usage recommendations

Use appropriate cutting lubricant with taps and dies to reduce heat and tool wear. Inspect tools regularly for wear or damage and replace inserts that do not seat correctly. For critical or load-bearing applications, verify repaired threads meet the required mechanical specifications and consider professional rework if necessary.
