How to use this expanding fixing?

[purpleroad]

Was going to use one of these fixings. I drilled a hole a bit wider then pushed it in. Then tried to turn screw so the metal in hole expanded outwards with outside bit hammer in so it digs into wall. Is that correct?

Is that correct?

Yes, but it can often go wrong and start rotating in the hole, especially if you've never used them before. It'll be SO much easier for you with one of these...

Also, the one in your picture looks like it is for double skin plasterboard. Do you have doubled skinned walls?

Yeah, it's one of the longer ones. Is it supposed to go behind the back (2nd) plasterboard and expand behind it? I am using it in these brick sized white soft things which are more crumbly and normal brown plugs don't get a great fixing in garage- will send photo. They arent as hard as orange bricks. I used a shorter one before in crumbly old plaster (in an old house) where the hole was big and it worked well,

Use a setting tool - no compromise!

Not a description of any building material I have seen.
What’s the garage made of?

OP - you know these are for hollow plasterboard walls yes?!?

As above - these are for hollow walls ......the thickness of which is determined from the screw head until the first corrugation of the fixings shaft. I find lots of these that are the wrong size for the wall so they remain loose.

You might like to try shield anchor/bolt (don't over-do the tightening or the block will crack) propr plugs for lightweight blocks or even chemical fixing if you can get the drilling dust properly clear (compressed air or blowing tube)

Been trying to use the expanding screw( as in pix above) and without the screws which they both come with. Trying to use a longer screw to account for the shelf bracket's length as well

 

[purpleroad]

Tried these as well. Hardcore screw.
Anyone know material am drilling into?

This bolt/screw thing is really strong. Just put it in.

The other two were pulling out of hole or turning when I tried to do screw up. The plug is 10mm so hardcore

The only correct fixing here is the plastic plug.....the other is a hollow wall fixing, and the one in your small pic is a plasterboard fixing.
If you are using a 10mm plug, use a 10mm drill, deep enough to accept the screw along its length. Thunderscrews are another option for good quality substrates - they cut directly into the block without a plug.

So u would use a seriously thick screw for those 10mm plugs? Where would u get those?

The plasterboard and hollow wall are the wrong ones? The expanding on (I believe called it hollow wall) was what I was recommended by a chippy in b and q.

What is this soft brick anyhow?

 

[foxhole]

Your "hardcore" screw is designed for use without a plug, small hole the diameter of bolt without the thread, which is why it does not hold.
The rest are not for solid walls apart from the plug which looks to be much too large for the job.

 

[purpleroad]

Think the chippy recommended the expanding fixing because of the soft brick.

You need some of these - select the correct size for your application

Or resin stuff:

Which is supremely good for heavy weight fixing thigs to lightweight walls (using threaded rod). The hole must be completely dust free though

(Use blow pump or compressed air)
