Ball end hex bits

[PositronicRay]

I can see where they're useful, but are they more likely to strip a head or weaker if access isn't a problem?

Thx std jobbies it is then.

Thanks.

I've damaged one, though "making do" with the wrong tools, long hex bits ordered. I've also ordered some Irwin bolt grips. Hoping I can get the damaged allen bolt out without further dismantling.

If the bolt is now a bit stuffed, a torx one size above hammered into the allen head can work well after doing the above first.

Good luck.

Thanks, hence the Irwin bolt grips on the way.

Particular hex head can't be seen only felt, so needs a decent long hex socket+extension.

My bodge tool was a short hex bit, the head off an impact screwdriver and an extension. It worked okay on the other fixings, but due to restricted space this arrangement didn't go in square. I thought I'd cracked it loose only to discover I'd stripped it.

As above, ball ends (OOOH ERRR MISSUS!) are just for winding in/out, the straight end is for applying torque.

Not trying to be "sucky-eggy" but when an allen bolt/screw is tight, I tend to take a bit of time with a small sharp screwdriver to make sure the "hex hole" is completely clear of rust etc. before trying to make sure the driver is as well in as it can be. Also a good smack with a hammer helps to break any stiction on the bolt/head.

Got the little bd, broke a couple of lugs off the old pump to give me access, then a combinations of Irwins (which I couldn't get to grip properly) and an impact screwdriver saw it off.
