Useful Helicoil kit
Usede to use helicoils many years ago and was delighted to get these at a resonable price. Used to repair an aluminium casting that had the 8mm thread damaged. Tapped to 10mm inserted helicoil using a bolt with slot cut in as do not have insertion tool. Workd brilliantly and a saved having to replace a costly unit.
