Thread Repair Kit GEKO M5 x 0.8 mm – set of 10 taps and 40 inserts

GEKO Thread Repair Kit M5 x 0.8 mm contains tools to restore damaged or worn internal M5 x 0.8 threads in metal and alloy components. The set is composed to provide multiple repair operations: it includes 10 taps and 40 helically wound thread inserts designed to reproduce original thread dimensions and restore the load-bearing capacity of threaded connections. The kit is intended for maintenance and repair tasks in automotive, machinery and general workshop environments where M5 fastenings are present.

Advantages

The kit allows repair of stripped or worn threads without the need to replace entire parts, which saves time and material costs. Using helically wound inserts provides durable metal-to-metal engagement and improves resistance to wear and vibration in repaired threads. The included quantity of taps and inserts enables multiple repeated repairs and reduces downtime for frequent maintenance tasks. Components in the set are matched to the M5 x 0.8 specification for consistent thread geometry.

Suitable for

• Repairing stripped or damaged M5 x 0.8 internal threads in engine components and brackets
• Restoring threads in machinery housings, gearboxes and industrial fixtures
• Maintenance and repair work in workshops and vehicle service garages
• Strengthening threads in aluminum or soft-metal parts subject to repeated assembly

Key specifications

• Thread size: M5 x 0.8 mm
• Contents: 10 taps and 40 helically wound thread inserts
• Intended application materials: steel, cast iron, aluminum and common alloys
• Insert type: helically coiled wire inserts for restoring internal threads
• Use case: repair and reinforcement of internal threaded holes

How to use

Prepare the damaged threaded hole by cleaning out debris, corrosion and any loose material. Use the appropriate tap from the set to re-cut or chase the existing thread to the correct M5 x 0.8 profile, applying cutting fluid as required for the substrate material. Install a corresponding helically wound insert into the tapped hole following the insert manufacturer’s direction: wind the insert into the tapped thread until its top is flush with the workpiece surface, then break off the tang if present. Verify thread engagement with an M5 bolt and torque to the required specification for the assembly.

Usage recommendations

For best results, conduct repairs with proper cutting fluid, a stable tapping fixture or guide to ensure perpendicular alignment, and a calibrated torque screwdriver or wrench when verifying repaired connections. When working on critical engine or structural components, confirm compatibility with the base material and follow the assembly torque values specified by the equipment manufacturer.
