Dear Expert
I uses Ramset M4 x 8mm Hollow Wall Anchor
At a bathroom to install new a toilet roll holder,,,,,I bought the one in the link above assuming the thickness of plasterboard is 13mm
I followed the installation instruction on the box (attached) it says :
1- Drill an 8mm diameter hole into the substrate
2-Tap the anchor into the hole until it is flush with the surface of the substrate
3-,,,,,,etc
I tried to use two wall anchors both of them their legs not expand like the fifth attached photos (from Bunnings website) and hence
the anchors were spinning inside the hole
Thx
Hi @zillah
Your problem is fixable a couple of different ways.
All we need to do is stop the anchor spinning in the wall so the metal starts expanding and grabbing the wall behind as it was meant to.
1 ) If the anchor can still pull out with out force i would wrap some tape (any tape) around the shaft just behind the large flange enough so when you reinsert it into the wall the anchor dosnt rotate at all just so you can use a screw driver to activate the clamp. Instead of tape a strip of paper wrapped around might work to if it willl fit in the hole making a friction fit.. If fit too tight shorten paper strip or tape so theres less thickness to the shaft.
2 ) with a pair of pliers grab the large flange and hold it while you have some one turn the screw to expand the anchor enough so it starts grabbing inside the wall as it was designed too,
3 ) Take anchor out and add some glue (probably any glue) to where the back of the large flanges shaft touches the inside of the wall. (not all the way along the fastener.
Good luck hope this helps
Thx Jewelleryrescue for the informative details
Hi @zillah,
Any of @Jewelleryrescue's ideas should work, but the easiest is likely number 2.
If you stick the anchor just past halfway into the wall, hold the flange or the shaft with some pliers, and get the expansion started. Once it has started that little bit, put it fully in place and continue to rotate the screw.
Oftentimes you just need the screw to start biting that little bit to get things going.
Let us know how you go.

Thx Jacob
will try that
Hi @zillah,
I thought I'd add that when inserting, you might need to press the fixing in firmly or give it a little tap with a hammer. The fitting has two pressed teeth, designed to bite into the plasterboard and stop it from rotating, allowing expansion.

Hi Mitchel
Attached instruction says “anti-rotation barbs “ but those got snapped when i was relying on them to prevent spin
Hi @zillah,
If you don't have any luck with the troubleshooting steps above, this Ramset Hollow Wall Anchor Setting Tool is designed for use with these anchors.
It would be worth looking into.

Thanks @Jewelleryrescue @JacobZ @MitchellMc,,,,,,I applied the below method
2 ) with a pair of pliers grab the large flange and hold it while you have some one turn the screw to expand the anchor enough so it starts grabbing inside the wall as it was designed too.
I am considering to get this as well for future use
