Is there a M5 thread restorer?

[PoorOwner]

I just realized my craftsman thread restorer kit stops at M6 bolts.
I need to "clean up" a M5 x 0.8 pitch.

Is my only option to buy a tap?

I have never seen one. I use Time-serts for that size. Its a very popular size screw on Husqvarna chain saws.

Never seen one. Have several taps for that size.

Can I cut 2 slots on a spare M5 bolt with a dremel cutting wheel?
will that create burrs that make matter worse?

I have a tap from HF tap kit but the quality does not look precise at all, could make things worse. I just need to get out the debris and maybe realign the thread.

If it was larger bolt size id say go ahead but dealing that small you could make a small problem bigger. If your worried buy a better tap.

Use a triangle file or the corner of a flat file. Ive done it many times on large bolts and odd thread sizes. I prefer to cut 4 slots but on something that small 2 or 3 might be better. Dont cut them too deep or you risk break the bolt off since its so small. You could probably even flat file the threads off 2 opposing sides since putting slices across the threads might be difficult

Works great, just dont force it.

If you can, use a thread chaser/restorer rather than a tap. No mater the quality of the tap, they can sometimes cut threads that you don't want Ken.

What's it holding?

If the threads are really messed up it might be easier to drill & tap one size larger - a #12 screw would be the next size up.

You beat me to it! I picked up one of these at Sears not too long ago & will be doing a review on it

Thats my idea for what you will need also.

You realize that this is what he's looking for in the OP, right?
