Source for thin spanners

Jan 15, 2007 16 Replies

Hi Chaps,



I need a 7/8 inch spanner that is thinner than 4.5mm thick. This is so I can grip a thin nut without also gripping the locknut on top of it. This in turn is so I can undo them, because the thread they're locked to can rotate and there's no way to grip that directly.



I really don't want to make a spanner so can anyone tell me a place that supplies thin spanners ? I googled "thin spanner" without success but maybe there's a technical term that would work better ?



Thanks,


Don't know the spanner widths used on Brit bicycles, but thin spanners are often needed for bicycle repair. So I would have a look at that kind of shops. Or grasp for my angle-grinder ...

Bicycle spanners used to be made from pressed steel, and should be thin enough. Whether you can find a 7/8" one is another matter.

Try a cycle shop.

There used to be all sorts of sizes of cycle spanners about 1/8" thick if I remember right -- cone spanners etc. Maybe a 'well-established' shop might still have some ?

I might have some 'somewhere' if you really don't want to make one,

Cheers, Peter W.

Yeah. It generally involves a normal thickness spanner, and a grinder ;-)

I don't think I've ever seen any thin spanner in any catalogues, other than cycle ones...

If all else fails, 4mm gauge plate, hacksaw and file a 22.3mm or so wide gash into it. Cheapest spanner you can find and an angle grinder.

in the bicycle world, they're known as "cone spanners", but I've not seen one that big.

The Taig/Peatol lathe spindle spanner is less than 4mm thick but is 1"

- I suppose you could braze on a strip of 1/8" material to pack it out...

When I had a similar requirment I hacksawed a slice in the thickness off a normal spanner.

Other people prefer grinders.

Good spanners are available cheaply and in quantity at car boot sales.

Angle grinder spanner and grind the locking tabs off?

(how you will next change the disk in your grinder is left as an exercise for the reader ;-) )

Do you need the spanner for opening the nut? In most cases not me, even without a quick-release nut.

Thanks all for the suggestions. I had already thought of bike spanners but they're all metric nowadays and I couldn't find a 22mm one to file out. I'll just have to make my own out of thin plate as suggested here. (I really can't believe I have to make a _spanner_ now of all things :-( )

Thanks again,

.....and I really can't believe you've spent so much time and effort deliberating when you could have made something from scrap in about ten minutes! :-} --

Hi Nick,

being a desk based IT wonk during the day means I have not the muscle power to rip the disks out of my grinders, so I do indeed use the spanner.

Also, all my mangle grinders are far too cheep to have quick release nuts on them :-)

Might be more than you want to pay, but I got one of these because it was simpler than turning up a replacement for a lost nut:-
