OK, I've decided to get a different type of lock now, but I'll bear that
in mind. I did notice somebody mention cheap tools in the Amazon
reviews for rivnuts, but said that they got better results by screwing
a bolt through, then holding the bolt in place with one spanner while
using another to tighten a nut down onto a couple of washers on the
rivnut.

The snag is you have to prevent the rivnut from turning - at least until
it gets a grip. Really with the Silverline tool costing about 20 quid and
with all the adaptors needed for the common sizes it's hardly worth the
bother.


These are very good (and can be used in tight spaces)

I've also had problems with the £10-£15 "gripper" ones, but not yet felt
the justification to spend £50 or more.
