Having just had a neighbour's break-in (keys to car stolen, nothing else), and
caught on camera several quite open casing-the-joint forays into our between
the houses passageway (my Audi's next, apparently), we've just had a metal
gate fitted. It's fine, quite substantial.

However, the latch and hinges are fitted with easy to remove hex nuts (fixing
the adjustable screw hinge) and bolts (holding the latch and hinge pins to the
brick wall).

I'd drop a spot of weld to the various bits if I had the kit and skill - but I
don't. Any recommendations for a supplier and type of secure nuts and bolts?
They don't have to be the last word in security - really, the padlockable
latch isn't that secure.

Cheers, Rob
