Rated 2 out of 5 by from Did not work as expected Sorry, picked these up on Saturday, based on excellent reviews. I needed to fix a towel rail into plasterboard, so drilled an 8mm hole as per instructions, inserted a no8 screw and turned. Unfortunately it just kept turning and never locked up, so I had to drill it out and repair the plasterboard. Will fix a batten to the timber uprights and fit the rail to that. So far, I am not impressed with these amazing fixings!

Rated 5 out of 5 by from Better than expected I had to carry out an emergency repair on the handrail on our stairs. The bottom bracket fits to a brick wall, but the top goes on a hollow wall. I had previously used the self-tapping screw-in type fir the top: they held for about 10 years, but our extra lock-down weight has had its toll, and they were never 100% secure. I knew this wasn’t the strongest solution but I don’t have the tool for the best option so thought I’d give these plugs a go, albeit with low expectations. I’m amazed at the security of the fitting. It really is solid, and hasn’t budged a millimetre over the weekend. I think I would have preferred a slightly narrower plug, but otherwise these seem to be quality.

Fischer UX and Duopower wall plugs, what is the difference?

Asked by: Sarracino

Screw Diameter

Product specs state: "Suits Screw Diameter 4.5 mm"....shouldn't this product be a better match for a 6mm dia screws? 4.5mm is too thin and would usually use a 6 or 7mm plug for that. Please confirm if this product suits a 6mm diameter screw. Thanks
Asked by: Alibabba
The Fischer website states that UX8 Wall Plug will accept screw sizes from 4.5mm to 6 mm. I used 4.5 mm screws (as stated in Screwfix description) and they went in easily.

What screws do I need

Hi I am hanging a bike rack onto thermolite blocks. What screws will be best for this please
Asked by: 10Dale1987


I purchased these based on the feedback, however I have tried them on a sheet of plaster to see how they work and they slip - every time - they do not perform they way they are meant to perform - what am I doing wrong?
Asked by: Scope
1/ Drill Ø8mm hole in the plasterboard 2/ Now tap in the plug, it should require a little tap to go flush. 3/ You will need an Ø5mm or Ø6mm wood screw but importantly the screw needs to be at least 55mm long + the thickness of the plate/timber you are fixing to the wall. 4/ Place the plate/timber against the wall, trapping the plug and tighten the screw. 5/ Make sure there is enough room behind the plasterboard for the screw to go and not hit whatever is behind Any issues, please email

What length of screw should be used?

I am looking to hang picture ledges as mentioned in a previous question, onto 12mm plasterboard, what length of screw should be used?
Asked by: Ross1984
Hi Ross The screw should be long enough to penetrate the plug. So has to be at least 65mm + the thickness of what you are hanging. Best Regards Technical Team
