Screw Thread Inserts

Helisert Screw Thread Inserts are made of helically coiled 18-8 & 304 stainless steel & Inconel x-750 wire with a precise diamond shaped cross section to accommodate internal and external threads simultaneously. When assembled in a tapped hole the insert presents a permanent internal thread which conforms to standard specifications.

The inserts are available in two basic types - STANDARD (free running) and SCREW-LOCK (interlocking locking).
