Description
Overview:
The M6 x 1.0mm Thread Repair Inserts (pack of 25) are wire‐form inserts used to restore worn, stripped, or cross‐threaded holes back to a strong, standard M6 x 1.0 thread. Made from corrosion‐resistant steel, the coils compress during fitting and then expand to lock into the prepared hole, creating a durable internal thread that often exceeds the strength of the original, especially in softer materials like aluminium castings. This Genuine Part is suitable for routine maintenance and repairs on construction and garden machinery, including engines, gearboxes, pump housings, mower decks, and handle mounts. Ideal for workshops, mobile engineers, and DIY users who need a reliable fix without replacing expensive components.
Key Features:
- Genuine Part for dependable performance and consistent quality
- Restores damaged threads to standard M6 x 1.0mm for easy bolt compatibility
- Wire insert compresses on installation and expands for secure, permanent anchorage
- Corrosion‐resistant steel construction for long service life in workshop and outdoor use
- Strengthens threads in softer alloys (e.g. aluminium) and reduces risk of future stripping
- Helps avoid costly part replacement; maintains serviceability of engines and housings
- Pack of 25 inserts supports multiple repairs or stocking for site call‐outs
- Suitable for a wide range of construction and garden machinery
- Smooth, free‐running internal thread for accurate torque and reliable clamping
- Compatible with standard M6 fasteners; install using appropriate drill, STI tap, and driver
Typical Applications:
Used to repair and reinforce M6 threads in engine covers, crankcases, gearboxes, brackets, guards, pump casings, and accessory mounts on compactors, generators, lawn mowers, brushcutters, pressure washers, and similar equipment. Ideal for restoring serviceability after seized bolts, over‐tightening, or corrosion damage, both in workshop rebuilds and on‐site repairs.
