What are these screws called?

[markyyyyyy]

Hi, what are these screws called?
I am installing a very heavy column radiator using core fix plugs. The screws that come with the core fix don’t have flat heads, which I need to act as a washer effectively.

Does anyone know where I can find the screws below… 3mmx100mm or 3mm x 90mm ideally

Cheers

Hex flange coach screws

Why not use some tapered washers eg https://www.amazon.co.uk/dp/B0CHW4X...=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM&th=1 rather than buying different screws which may or may not be a perfect match.

Could a 'penny' washer provide a large head ?

Are these what you're screwing into dotdab plasterboard as per your other thread ? Surely t f not !

Why not? They're designed for d&d.

You don’t need a flat head , just use a washer .

Exactly...perfect for the job.

I'd agree with this comment. The threads are not coarse enough for plasterboard and tbh, I wouldn't trust anything hanging off of plasterboard anyway. Anything heavy, kitchen cabinets etc and these rads that you suggest, I would drill through the board and direct-fix into the substrate behind, personally.

I’m very surprised Freddie and Kool would screw these into plasterboard and hang a radiator on them !

entirely the wrong thing for plasterboard

It's a bit embarrassing that some of you don't know what corefix's are. Heyho.

Have a look at the OP’s other thread and photo of what his Corefix has achieved so far …….

 

[freddiemercurystwin]

I have, he's got a dot and dab on masonry and he's made a hash of the holes, he just needs to fill the hole and carry on with the corefix.
