SPREW / Helisert

Used in place of screws in fasteners where the base material is light alloy, plastic or wood. There is an advantage that the adhesion can be increased without impairing the durability of the base material. In addition to helping to reinforce and prevent damage to internal threads, it also strengthens the fastening force. The sprue helisert itself is made of metal such as stainless steel. The sprue and helisert tap holes are larger than the base metal tap holes. The mechanism is designed to increase the degree of adhesion with the base material by utilizing the property of screwing into a small hole with a dedicated insertion tool and returning it to its original position. Used for aviation parts that require light weight and durability.
