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 helicoils are available as individual coil inserts or as a kit. The 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.
A hexagon bolt, or hex bolt to give it its more common name, is a threaded bolt with a plain shank and hexagon shaped head.
Metric fine thread is a common thread, often found on machine screws. More threads per axial distance (length along the fastener) than metric coarse. A fine thread is known to be stronger than a coarse thread.
