Fischer metal fixing

[mjtefc9]

Hi.. I've put a metal 35mm self drilling fixing in my drywall to hang a shelf.. But it just kept spinning and never bit and left a hole The position is where it has to be so I can't really reposition it.. Any advice on getting it to stick so I can screw into it??

They usually spin when they hit an obstruction preventing full insertion, or when over tightened, remove by unscrewing and try a nylon version [can be glued in] though most likely the hole is now too large to hold it, what are you installing.

Time for a new fixing.....try googling toggle fixings, or hollow wall anchors?

Brill thanks John.. So will they just fit in the larger diameter hole?

The toggle fixing in particular is good for holes that have become oversize.....basically the 'wings' are pushed through the hole, where they flip out under spring pressure. Tightening the fixing causes the wings to lodge in the plasterboard underside.
You only get one chance with these though, its almost impossible to draw them back again!

Sound just the job!! I've actually put filler in the hole and lodged the fixing at the moment.. I was hoping it may harden and the fixing be good enough to screw into.. But I can't see that happening !!!

Me neither, but it'll help to secure the new fixing - plan B!
One small issue with the toggle fixing.....the centre screw doesn't want to poke into the solid wall behind the plasterboard - it can be cut to length if necessary so have a think and maybe a trial run before going for it!
Hope it goes well
