poxy wee grub screw allen bolt in my grips is being a right bawbag. anyone got any ideas how to shift it? its on the verge/could be rounded. tried soaking it with wd and not really wanting to force it much more. bloody halfords crap.
Hot water (I'm assuming the collar is alu).
never heard of that! I will try it when my patience returns. Thanks!
What Roschach said, if not use a hex bit if you have one then you can push down on the ratchet whilst applying more torque, if not just go for it if you **** it just drill the head of the bolt off using a drill bit the same size as the head of the bolt.
Thanks!
I have a similar problem but with a crank bolt that I cannot shift, do you thinking the hot water trick could work? I assume that the steel bolt expands less that the thread in the axle, freeing it up? Or just the expansion contraction has a loosening effect?
Before the drill, you could try forcing a Torx bit into the head. After all, how much torque did you use to do it up? Other wise, driller time!
bit of 'plus-gas' makes a lot of inroads into a siezed bolt.
Then a hand held impact driver. You can get one that will fit your normal sockets/connectors etc.
+1 plusgas. it really is magic.
If it's a tiny grubscrew that the allen key is just a bit loose in, get an allen key of the right size (one you can spare) and hit it with a hammer to flatten it slightly to get a better fit.
Hot water = waste of time.
Plusgas/WD40 etc. = waste of time, it won't penetrate seized threads.
Hammering in a bigger Allen key will destroy it.
Cutting off the head will leave the shaft and how are you going to remove that?
The answer:
Support the piece very well. Take an Allen head from a screwdriver set or a punch and a big hammer and give the bolt a smart tap vertically.
Having broken the bond you'll find that it will unscrew easily.
Thanks again all.
