anyone used a helicoil before

It is obvious that threads are not your strong suit.

:lmao: I get it.


TT is quite correct. Moving up to the next standard size bolt is not a good idea, and in many cases simply not possible. A helicoil is the simplest, most practical, and ultimately, the only solution.

Yes me again. You are the person that put up a link to a 6.3 mm tap. I have never heard of such a thing but I do know that is not the size needed to tap a 6mm thread. If the thread is stripped then there is no material to be cut by the tap anyway. The OP stated that the thread was stripped not cross-threaded and The best fix for this is a helicoil. With more than 40 years experience in engineering and having worked with all types of threads including roll forming, cutting and grinding on many different materials I feel I have enough knowledge to add to this thread. It is obvious that threads are not your strong suit.

no such tap in this chart as 6.3mm, it's 6. When providing that link I presumed it was a typo by the vendor. I stand by my recommendation to fix the threads if possible with an m6 tap. If not go to the closest tap the next size up in standard or metric. This will work and cost less than 10 bucks.

I get it to, trolls.

The problem with a fix like the one you suggest is that, at best it is a bodge up. Chances are that the fasteners on a valve cover are socket heads not hex heads therefore the valve cover would need to be drilled and counterbored oversize to suit an 8mm screw if there is enough material surrounding the hole in the first place. This leaves you with a bastard valve cover and the need for two wrenches next time you do any maintenance. Throw in the time and expense of the valve cover work and the helicoil becomes a much better proposition. I suspect that the OP has long since fixed his problem with a helicoil and is happily riding now.
