What are HeliCoils?
A HeliCoil, otherwise known as a screw thread insert or helical insert, is a registered trademark of STANLEY Engineered Fastening. It has a stainless steel wire that has a diamond-shaped cross-section and repairs stripped thread in hard metals such as steel or soft materials such as wood or plastic. HeliCoils create stronger bonds than the original fastener because they are coiled wire inserts that are wider than the tapped hole. When you insert them into the hole, and as you screw the bolt down, the coil tightens and creates a seal. As a result, these inserts prevent wear while boosting the integrity and lifespan of its application.
