Tool suggestion to remove these damn things?

[GreenV8S]

I don't recognise it, but it sounds as if it has been deliberately designed to not be removable by standard tools. Are you sure you want to remove it?

At that size, it should be practical to grind a key out of some quarter inch plate. Either cut a square hole in to take a half inch drive, or weld a bar to it for leverage.

Any pictures of it?

What about the old plumbers wrench, Footprints?

[Mignon]

I suggest you get an offcut of 1/2" steel or aluminium about an inch wide. Mark out the shape of one of the bolt head points on this and hacksaw or angle grinder it out. Then you can put this over a point on one side of the bolt head and use a big adjustable spanner or plumber's wrench to hold this together with a flat on the opposite side of the bolt.

Do you need to save the bolt.

If no why not try something like this ?

Careful I ended buying both sets as the sizes are odd

Knipex pliers have a good reputation for gripping to anything.

A Lexus spare wheel socket has 5 sides? 23mm though I think?

What’s it on? The tool must be available somewhere to remove it?

As suggested it's not normally meant to be removed.....




It's not really a bolt as such, I just used that word to provide the right imagery. It's the fixing on the water caps. Of course the US fire department have their hydrant tool to open them, but as we don't use these hydrants in the UK I can't get the tool.

It's getting disassembled to be blasted, painted etc, if I can get the damn thing apart.

Welding something isn't much use as it'll be a display item. I suspect that the oil filter wrench won't work, and the stillsons won't grab well as they have parallel opposite jaws.

Does it really need undoing?

Personally i'd have the shape laser cut out of a piece of (maybe hardened) steel and make a tool out of it.

[GreenV8S]

I don't know if they're the right size, but ebay.com (US) and ebay.co.uk (UK) show similar looking fire hydrant spanners/wrenches with five-sided openings that look as if they might fit.

Nice big stillsons will soon shift that.
Not much a nice sharp pair won't grip.

[stevensdrs]

Take a 1" piece of square iron bar and grind a V into it. Then place the v cut over the sharp bit of the 5 sided thingy and you have 2 flats to put a big spanner on. Simples.

Mole grips with curved jaws.

Assuming you can get 4-foot mole grips!

One of those sockets that have pins in them that get pushed back as you push it onto the nut?

Again This ^^^^^ They will grip and turn a steel tube , so absolutely will remove the hydrant cap
