Thread Repair Kits

Thread repair kits restore stripped, damaged or worn threads in a workpiece without replacing the entire component, using an insert or coil to rebuild a strong, usable thread. RS Australia stocks thread repair kits across several insert systems to suit a range of materials and thread sizes.

Repairing a damaged thread is often faster and more cost-effective than replacing an expensive housing, engine block or structural component.

Types of Thread Repair Kits

RS stocks thread repair kits across coil insert, key insert and tapping systems to suit different repair scenarios.

Coil Thread Inserts

Coil thread inserts are wound from diamond-shaped wire and installed into a tapped hole to create a new, strong internal thread. These kits typically include the coil inserts, an installation tool and a tang break-off tool.

Key Thread Inserts

Key thread inserts use a solid insert with locking keys that bite into the surrounding material, offering a robust repair for higher-load applications where extra holding strength is needed.

Tapping & Drilling Sets

Tapping and drilling sets prepare the damaged hole for insert installation, ensuring the new thread is cut cleanly and to the correct specification before the insert goes in.

Applications of Thread Repair Kits

Thread repair kits are used wherever a stripped or damaged thread needs restoring rather than replacing the entire component.

Automotive Repair

Automotive workshops use thread repair kits to restore stripped threads in engine blocks, cylinder heads and other components without needing a full replacement part.

Industrial Maintenance

Maintenance teams rely on thread repair kits to fix damaged threads in machinery housings and equipment, minimising downtime and avoiding costly component replacement.

Plumbing & Fabrication

Plumbing and fabrication work uses thread repair kits to restore threads in pipework and fittings, keeping installations functional without re-machining the part.
