I have some solar panels secured to the roof of our boat by lengths of studding in tapped holes in the boat roof. Is there any 'clever' way I can make it difficult to remove the nuts holding the panels to the studs? E.g.is there any sort of 'security nut' akin to a security bolt that needs a special spanner to undo it?
Things akin to car road wheel studs which need special spanners won't work very well as I don't really have easy access to the 'end' of the nuts as it were.
You can get nuts that have the hexagon bit attached via a neck to the rest of the nut. You do 'em up and the hex bit shears off at the neck leaving a round conical bit behind holding the kit down.
Screwfix have 'em in A2 stainless and this is for a boat...
You mention wheel nut type things so do you envisage a routine requirement to remove them? Shear nuts would be a bit of PITA for that and are single use.
Bung "security nut" into google for other options that are releaseable.
You can get security nuts where the ends shear off when you tighten them.
There are also removable security nuts which require special tools such as :-
Well there is Drivel and dennis. And Farmer Giles
We THINK they are secure.

Locktite?

When I saw the sub line I thought of a cricket box.

If it is to stop theft then use studding with a left handed thread, that should thwart 99% of petty tea leaves.
He he, it probably would as well.
On it's own it's not that good, even the ones that are supposed to be unremoveable. Now an "unremoveable" thread sealing compound and a LH thread...
Trouble is it would fool me most of the time as well! :-)
Se where do I buy stainless studding and nuts with LH thread?
I don't think it would be that effective anyway, a scrote with a socket spanner will chimp them off in no time, shearing the studs in the process.
Stainless shear nuts, as mentioned already, would be my choice.
These we use for palisade fencing, our fitter also has a tool that unscrews the cone ;-)
It is also used to remove locking wheel nuts.

I was thinking along the same lines. The penny would drop eventually, but probably too late.
You could also alternate left and right hand theaded studs.
