Usually with studs rather than bolts. You glue the stud in place,
leave it to set and then bolt up later. Rock climbers have
"interesting" opinions on the virtues of these.

Fischer are probably the best known maker of this stuff (I imagine
their website is informative). You can get them from most big hardware
suppliers, inc. the inevitable Screwfix.

You need some studs:

(many varieties)

And some polyester resin as either a big tube

or individual servings

There's a lot of economics to think about here, cost of using
expensive single shots vs. the high initial and lower individual costs
of the big tubes.

These are worth using, if you're doing a bunch of holes in crumblium,
as they can save a good price of resin

Don't make your own studs from studding unless:
* It's M12 or bigger
* It's cut with a decent thread, not the usual badly rolled V-crested
rubbish
* You degrease it with acetone before use.

The thread profile for a resin fixing is _not_ your standard fastener
thread. In particular, trapped air on that thread will lead to a very
weak fixing.
