Free Running Helical Inserts

Free running inserts are designed to make threads or repair worn threads inside tapped holes. They are ideal for providing reliable threading in metals, composites, wood & similar materials. These inserts are usually larger in diameter than tapped holes and are compressed while being inserted, thereby providing maximum surface contact area. Raptor Supplies offers a wide range of free running inserts in Metric, UNC and UNF thread types from Chrislynn and Heli-Coil.

Frequently Asked Questions

How to install helical inserts?

  • Drill a hole using the suggested drill bit size.
  • Tap the hole and screw the insert into the installation tool. The prong must be properly engaged in the driving contour of the tool.
  • Using the installation tool, thread the insert into the hole. Install the insert a quarter to half turn below the hole's surface.
  • If your insert has a prong, remove it with a punch or break-off tool. This allows the screw to fully enter the insert.

Where are helical inserts without prongs used?

These inserts are frequently used where debris could cause damage because there is no prong to break off and retrieve. They have coils that expand after installation to secure the insert.
