strong wall anchor for 6mm plasterboard

s7ryf3925pivug

My internal walls are all plasterboard and it looks to be about 6mm thick after drilling a 10mm hole for a plug.

I used these to secure a standing shelving unit in place and it was fine because it expands out but the arms wouldn't actually reach the back of the plaster so it's not as strong as it would be otherwise

Most hollow wall plugs are for 9mm plus walls. Any heavy duty ones suitable for 6mm plasterboard?

What's the distance between the plasterboard and the wall? Fix into the wall no?

They're hollow walls. Plasterboard on a timber frame. I can find the timber frame and use that where possible, but very restrictive to try to do that exclusively.

Try gripit or geefix fittings. Either should do what you want. The latter I believe is stronger.

gripfit data sheet says suitable for all plasterboard types (9.5mm to 15mm). My plasterboard is 6mm though so probably not.

Geefix says it works with material between 3mm and 75mm so it is suitable.

It needs a 1 inch drill bit. Can't picture that.

Would spring toggles work? Geefix looks like the same basic idea though implemented differently.

Geefix is incredibly strong. I think they tested stronger than the toggles. I don't believe the holes have to be one inch. Check out YouTube.

Was going to say spring toggles

Only problem is you need a large drill bit

6mm plasterboard? Isn't that only used on bendy walls?

Well the wall isn't bendy so I guess not in this case. 1970s bungalow. Might not be exactly 6mm (and I put a plug in the hole I drilled) but it was closer to that than 9mm.

cool finally found a 1" drill bit with an sds shank that didn't cost lots, so ordered it and the geefix. Thanks again saved me lots of time.

Seve OB

these are the best things I've used. can get them in all sorts of sizes. I wouldn't bother with any other fixing anymore

Cool. I've a load of diall ones in that style but they say they are for 9mm min thickness. Those ones work with 2mm plus though according to the official site.

Are the spiral ones metal or plastic no use to you ?

Deals have plastic ones for 1.5 for 10.

I wouldn't go as far to say that they are rubbish. I agree they are not particularly strong, but used correctly by drilling the correct pilot hole they can hold a decent weight. People often insert them incorrectly they push them in too hard and soften the board all around them and compromising the grounds.

I've hung panel heaters in my own house with them with out issue, removed them last year.

Point taken though, tbh I find all of these solutions to be light weight. Where possible I'd drill straight through wall behind the plasterboard and carefully pop a rawl plug on the end of long screw and tap it home to get it into the concrete grounds behind, or search for a stud.

Geefix will work but you will need to reduce the thickness of the round plug which isn't that hard with a sander.
They are very strong and better than the gripit fixings.
Miles ahead of all the other types.

I don't really like the metal fixings, there's too much of a strength/hardness mismatch between the fixing and the plasterboard.

In my experience they just result in bigger holes when they fail.

These have their place, ive used them,

however they are more than useless in 9mm plasterboard
