Helicoil Type BSW Thread Repair Kit 9/16bsw x 12tpi with 1.5 D Thread Inserts

These VCOIL BSW (British Standard Whitworth) Thread Repair Kits work the same as Recoil and Helicoil kits. They are supplied with free running stainless steel wire thread inserts at 1.5 times the diameter in length and come in nice plastic cases to keep everything together
Instructions for use
Clear the damaged thread with a standard drill or use a insert extractor.These VCOIL kits include the correct size drill to prepare for tapping up to M12 (1/2") Check that the thread and pitch of the tap and the bolt match. Use the special VCOIL Taps for cutting the holding thread into the cleared hole. Please use a suitable cutting oil. Place the insert onto the installation Tool and position the adjustable ring so that the insert tang is centred into the tang slot. Wind the insert in with a gentle downward pressure until a half turn below the surface. Do not work against the thread direction as the tang could snap. For the Tang removal lift the installation tool and use a tang break tool or long nose pliers to remove the tang.Believe it or not, due to the narrow and exact tolerances the new thread normally is stronger than the original one.
