Nicely done! You make it look easy.

I broke one of the screws that hold the passenger headlight down on my 2004 Corolla. The screw was really rusty. I will try a screw extractor first, and this is Plan B.

Good reason to use anti seize whenever possible

I used an impact driver and the tip broke flat on the bolt for my rotors. I can’t drill it out. I need some tips

I have several bolts snapped off inside the thread where there is no way of grinding them flat but I can't find a single thing on YouTube regarding this subject. I don't mean to sound like I know it all because I certainly don't but, it seems obvious to me to grind the bolt flat it at all possible what do I do when it's not possible is what I'm after. I purchased eight very good aluminium garden chairs that I am going to re-spray. When it came time to dismantle the chairs I found, missing, bent and broken bolts. The broken bolts are awkward enough to get to with a drill let alone anything else. The bolts are stainless steel and are as hard as heck to drill. Any help you can offer would be appreciated.

So the tap bit will tell you which drill bit to use to pre-drill the hole before using the tap?

[Chris-dyiy]

Will it affect the operation of a machine if the bolt is broken inside? Once it is tighten inside it will not affect in any way?

[kevdog]

If the hole is stripped out could I use same size tap or do I need to drill it out and go larger?

[MrTruthislight]

So are you aren’t worried about swarfe getting in the engine?

[sinajetta]

can i drill a hole in a bolt that was broken inside an original hole? basically tap a new hole in a broken off bolt?

Doesn’t an m6x1 require a 5mm drill bit? I had to oder it specialty m6x1 tap and looked it up said 5mm, both had to be ordered in

[misterbulger]

Every one of my screws is stripped - any good way to figure out the thread pitch on your tap when you dont have anything to go off of?

[randallrogers]

Nice. Broke a bolt head off after work on the ol duramax. Saved me in a pinch. What's the stones song playing?

[kyroskiokas]

You screwed a new bolt but how did you get the old broken bolt out in the end?

[carlosybarra]

What kind of drill bits were you using??

[Zfour]

Will this get out a stripped oil drain bolt thats stripped inside the oil pan? Im thinking of creating a new drain hole and seal the old one

[ybrik]

Does that mean after drilling it out, tapping it to the very same threads as before?
