GGF released a good practice guide that has several good points.
https://garrardwindows.co.uk/pdfs/W&D_Good_Practice_Guide-4ec42d0c5aa21.pdf
Some bits:
Fixings should be at least as corrosion resistant as BS EN 1670:1998, Grade 3. Lots of people also forget that connections to steel over 2mm thick should be into pre-tapped holes with machine screws or alternatively with power-driven hardened self-drilling screws.
Polyurethane foam may be used as a supplement to mechanical fixings but should not, under any circumstances, be used as the sole method of securing the entire frame into the reveal.

The window fitter i know uses these kind of screws, straight into masonry.
In the old days there were some frame fixing Fischer plugs which would not pull the frame.
Don't know if they're still sold.
But the masonry screws are easier, providing there's an adequate packing up so the frame doesn't distort.

Not quite straight into masonry... You will need a 6mm ( if using 7.5 diameter) pilot hole in concrete block, brick and stone or they will just jam or crack the block/brick
No shyt sherlock.
Sorry mate, but do we ALWAYS have to state the obvious?
Straight into masonry = no plug required.
This reminds me of some instructions on a railway phone: to make a call lift the receiver, then dial the number, etc...

To DIY users that have never had experience of these types of screws.... Yes we do need to state the obvious in my opinion I'm afraid. I've had one of these jam and rip the drill out of my hand, throwing the drill out the window across the car park... That was with a pilot hole, imagine someone not used to using them and that happening... They'd be blaming that bloke on the forum for not warning them lol. Unfortunately it's the culture we live in today
