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.

They can be removed - but only with considerable difficulty.

There are also removable security nuts which require special tools
such as :-

http://www.shop4fasteners.co.uk/acat...curity_Nut.asp

These are always somewhat less secure than those which shear off.

http://www.securityfastenersandfixin...y-nuts-16.aspx

has examples of both.

Well there is Drivel and dennis. And Farmer Giles

We THINK they are secure.

If it is to stop theft then use studding with a left handed thread, that
should thwart 99% of petty tea leaves.

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...

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.
