- The key mechanically locks the rotation so there is no risk of it falling out.
- With high strength compared to coil-type inserts, it is usable for firm fastening or in areas where bolts are frequently fastened and removed.
- It is ideal for reinforcing female threading in light metals such as aluminum, castings, resin etc., as well as for repairing damaged female threading.
