Threaded inserts are often exposed to high loads. They must withstand significant amounts of force, vibrations and, depending on their location, weathering.
Over time, your Helicoil thread inserts may become worn, making them less stable. That means it's time to change them!
At Gardette, we know exactly how to repair your Helicoil inserts and thus extend the lifespan of your assemblies.
That’s why we’ve developed our own range of thread repair kits sorted by diameter. In these kits, you’ll find specific Helicoil inserts aimed at repairing threads for all kinds of applications. Inside these Helicoil thread repair kits, you’ll find a wide range of tools and accessories for repairing your threads.
All of our thread repair kits are sorted by diameter and sold with tools and accessories suited to each one.
Repair kits by thread diameter - Free Running
The classic Helicoil insert, compatible with UNC, UNF, BSW, BSF G (BSP), BA and NPT threads.
Both single-height kits and three-height kits are available.
Thread repair kits by thread diameter - Grip Screw
The grip screw thread insert offers superior impact strength and better resistance to vibrations and movement. It can be distinguished from the others by its red colour. We recommend using these inserts only when high strength is required.
Thread repair kits by thread diameter - Spark Plug
To repair a spark plug thread, it is not necessary to drill a central hole. That's where the HSSG combined drilling and threading tool comes in. The hole is widened by the drill bit at the same time that the thread is cut with a machining allowance. Our spark plug insert kits, sorted by diameter, are available in four lengths:
Thread repair kits by thread diameter - Drain plug
To repair the thread on an oil drain plug, use a twist drill bit to drill through the damaged thread. Then, if necessary, use a countersink tool to widen the hole.
These elements can all be found in our thread insert kits for drain plugs (by diameter), and are available in three lengths:
