Helicoil Kits - Metric

Helicoils, sometimes called recoils or thread repair inserts, are precision inserts that are most commonly used to repair damaged or worn threads. They can also be used to create strong new threads.

A Helicoil is essentially a free-running, stainless steel wire coil that is inserted into a hole with a thread that has been specially tapped to accept it. It is used to create a standard-sized, internal screw thread within the existing hole. Helicoils come in a range of different metric thread sizes.

Our Helicoil kits contain everything needed to install a Helicoil, including the inserts themselves, a drill bit and a tap, an inserting tool and a tang break off tool.

Please note that some of the larger sizes of helicoils do not come with a drill bit, this would need to be ordered separately. These sizes are for coil inserts above M12. Please check the description on the specific product pages for further details.

Metric is the most common thread type in production today. Usually specified as M then a number x another number. This signifies the thread diameter and the length of the fastener.

For example, M4 x 30 means that the major thread diameter (the external distance across the outside of the thread) is 4mm and the length is 30mm. Length is usually measured from the underside of the fastener head.
