oil filter bolt

The KZ400 I bought has a damaged oil filter bolt head. The PO apparently used way too much torque installing it, and so trying to remove it with the remaining material still present. Tried a 6 point socket but there's not enough bolt left to keep the socket from slipping. Tried large set of vice grip pliers, but they start to strip the head after a certain amount of torque is applied. Anyone run across this and been able to get out of such a screwup??

Can you upload a picture of the damaged bolt.
In a worst case scenario i would weld a bigger nut on the remaining bolt head.

I appreciate it. Actually, I just came in for the night and I'm happy to say that tonight I was able to get it broke loose. Of course the head is destroyed so now to eBay to buy a replacement.

I recently salvaged a oil filter bolt from the scrap bin by brazing on a nut works great now.

thanks. That's what my dad would have suggested, forgetting that my brazing/welding skills are sucky!! haha
thanks again.

Sometimes a smaller size Stillson wrench (aka pipe wrench) will serve to grip onto and loosen a buggered bolt. The Stillson wrench's grip gets progressively tighter as pressure is increasingly supplied. It's purposefully designed to loosen and tighten "round" pipes and round pipe fittings.

Good Fortune!

thank you sir! I actually ended up getting it off, but I have to buy a new one.
