HELI-COIL® Pipe Thread Inserts are precision formed screw thread coils of 18-8 Stainless Steel wire cold rolled into a sharp crescent diamond shaped cross section having a tensile strength in excess of 200,000 psi and a smooth surface of 8 to 16 micro inches. Prior to installation, the Pipe Thread is larger in diameter that the tapped hole.
In this design manual, the lengths are listed as multiples of the nominal thread diameter of the screw; 1, VVi, 2,2-Vi, and 3. This choice of insert length balances the bolt tensile strength against the shear strength of the parent material.
HELICOIL® Plus produces high-strength threads transferring forces from flank to flank into the holding thread. It is a highly reliable system for which German and international industrial property rights have been filed.
