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?

[one eyed mick]

They are good for running awkward stuff up and I suppose iffy in worn fixers use caution !!

Thx std jobbies it is then.

the ball end is a lot easier to get into the bolt, it kind of self aligns. This makes winding a bolt in easier and quicker, and if access is restricted can be used out of alignment. The standard end is then used for final tightening, using the long ball end for leverage.

The ball end is not meant for initial loosening or final tightening of a bolt.




If you are referring to these type of thing, I wouldn't use them if bolt feels very tight or needs to be done up very tight

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.

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.

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.

we use a lot at work on the assembly side. if using an assembly gun in tight corners where you can't get in straight on with the gun, they are invaluable.

normally use the WERA branded one. have a good torque rating you can use them upto as all our guns are pre-set.

I always use Hex bits in allen Bolts.

they seem to fit in tighter and and in my limited experience, far less likely to slip and strip the head

Made the mistake once of trying to loosen a tight bolt with a ball end bit - ball broke off and was stuck fast in the bolt. Had to destroy one of the parts with an angle grinder in order to get a bolt remover in place. Expensive mistake!

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.

Oh where was this thread a week ago!

Managed to break off a ball head in literally the last bolt that had to be removed when replacing a motorbike stator.

After various methods failed, a chap who used to be a bike breaker said to get a chisel and hammer on it 'it's never failed me' he said.

He was right too!

Never again - ballheads for locating, but never for tightening/loosening again.

That's what you are meant to use, did you mean to say Torx bits?
