Am I correct in saying that the rawlbolt specification screwfix use is
( thread x maximum fixture size), e.g. M12 x 60 can fix 60mm thick
fixture. It looks like that from the pictures. The B&Q ones appear to
be (thread x length of bolt) and the back of the pack tells you the
fixture size - since the bolt is usually 50mm, in B&Q, M12 x 110 is
needed for a 60mm fixture.
Does this sound correct ?
(Good news: a local screwfix counter has just opened (Nuneaton))
Thanks,
Simon.

it's the fixture thickness in Rawlbolt specs.

If you are looking at these kind of fixings, then I've found that
injection fixings are a much better solution.

- There is not the issue of the fixing not gripping properly if the
hole is not quite right or the material a little crumbly

- You can have whatever length you like

- *Very* sturdy fitting.
