I am not a machinist. I just discovered a method to repair stripped threads that is a fairly recent innovation--TIMESERT. The TIMESERT thread repair method is nicely demonstrated in this recorded presentation: https://www.youtube.com/watch?v=A4sS3T6g84I The TIMESERT method may be more expensive that other techniques. It looks like a kit for a particular thread sells for about $65. The kit provides --a drill --a counter bore --a tap --an installation driver tool --and five steel thread repair inserts If no errors are made, a kit should be able to repair five stripped threaded holes. The reference to time in the names appears to be due to the timing of the internal and external threads of the insert. This feature allows a very thin wall thickness in the insert. TIMESERT inserts are available in stainless steel for use in applications with water immersion. If you strip the machined threads on an outboard engine gear case oil filler hole, you may be able to use a TIMESERT to make a repair. |

Wow - I wish I had known about these kits when I dealt with the stripped plugs in my Ford... |

It looks like a fancy version of the age-old Heli-coil to me, with a flange at the top. |

I agree that the product HeliCoil is better known and has been around longer. The HeliCoil has been around so long and is so well known that even I, a non-machinist, had heard of HeliCoil and used a HeliCoil to make a repair. That is why I did not write an article to tell everyone about using a new idea to repair a stripped thread using a HeliCoil--I figured everyone had heard of HeliCoil. This thread is to inform people about the possible new idea of using TIMESERT to make a repair to a threaded hole. |

I have never heard of TIMESERT either but I have known about HeliCoil for quite some time. I just had to repair some stripped holes in my boat and I was concerned about using any kind of plain steel product for thread repair in the hull. I corresponded with the folks at HeliCoil and they told me that all Helicoil inserts are stainless steel. I forgot to ask what grade of stainless is used in the product. Although some grades of stainless steel do rust, any kind of stainless should be better than plain steel in a marine application. Are the TIMESERT inserts made of stainless steel too? |

Indeed, Heli-coils have been around for a long, long time - remember using Heli-coils 40-50 years ago. They are made of stainless - and I have never seen one rust. On top of that - they are a LOT cheaper than the $65 quoted above - and they are available just about everywhere - even at Wal-Mart. ---- Jerry/Idaho |
