The flexibility of our inserts enhances load bearing capacity by deflecting the residual forces into a helical direction, which is dispersed into the wall of the tapped hole.Each kit consists of the correct size drill, a tap, installation tool, tang removal tool and repair Helicoils, all in a plastic box. Compatible with Recoil and Helicoil Kits these VCOIL Wire Thread Inserts are manufactured from high quality chromium nickel stainless steel, to aircraft and aerospace standards. Our standard free running wire thread inserts are produced from Austenitic Stainless Steel wire (304/A2 Stainless), which is cold drawn (profiled) to form a diamond-shaped wire.

We are proud suppliers of all the leading cutting tool and tool holding brands from around the world. During installation the inserting tool applies torque to the tang reducing the diameter of the leading coil permitting it to enter the tapped thread. This wire is then wound into a spiral coil which when installed into Heli-Coil tapped holes, provides permanent conventional 60° internal screw threads.

Once fitted, the action of the radial pressure between the insertï¾’s coils and flanks of the tapped hole holds them in place securely. This assembled insert accommodates any standard bolt or screw (MIL-S-7742) and MIL-S8879 (UNJ controlled radius root) male threaded members.
