Powercoil Screw Thread Inserts are used to create high performance threads and to repair damaged threads. The unique design of Powercoil inserts creates superior, stronger thread joints whose compound performance cannot be reproduced by any other fastening system. Powercoil Screw Thread Inserts are much lighter and less expensive than any other equivalent type of screw thread insert such as Helicoil, Recoil, WTI inserts, or V-Coil.
