The Molly plug's screw just spins around

[xayidae]

After drilling holes and placing the screw in the hole, "expanded" the screw with a regular screwdriver, the screw just spins around and won't even come out again. What has happened, and is it even possible to get the screw out? So it's not the entire kit with the plug and screw that has spun around.

Tomorrow I'll buy that special tool, but for now, I just want to get the screw out so it doesn't stick out anymore!

Probably the plug is broken.

I can add that I have just screwed in two identical plugs and it's the same problem with both. It's not the first time I've screwed these from Byggmax but isn't that odd in itself?

 

[SBH]

nah. they should preferably be tightened with tools. you've just been lucky with the others.

 

[xayidae]

any idea how to get the screw out? tried with pliers but no...

 

[SBH]

well cut the screw and push in the remains.
try to pull the screw and at the same time turn it.
the screw only has the nut part left on it. the anchor itself is stuck in the wall, but not the nut.

Insert something thin (a Morakniv works or a thin flathead screwdriver) under the screw head and pry a bit so you can get the screw head out a little, then insert, for example, a pair of side-cutting pliers underneath. Unscrew and pry a little at the same time, and it usually comes out.

If you're unlucky, the broken wings spin (so they might break off) without catching, and then it can be a problem.

I've pointed out this built-in flaw in Molly's construction before. For a professional, it works, but if you're not one, it can easily go wrong, as in this case. A screwdriver is not recommended. Buy a special tool (not expensive) for the installation. It also works without the special tool, but again, you need to know what you're doing.

It's hard to remove an entire Molly plug without leaving unsightly holes if you're not experienced.

Then there's a tip not to buy that kind of thing at biltema or byggmax. Very easy to tear the thread. Spend a few extra kronor and get quality.

If you're going to pull them with a machine, it requires a bit of finesse. Not too fast and not too hard. Then there's really poor quality as well.

I bought something similar from Jula (a kit). The threads didn't hold. And in some, there were hardly any threads. So I bought better ones from Beijer.

These plugs can drive you insane, especially if, as mentioned, you buy cheap sets. I had problems with plugs from Jula that didn't want to work despite being mounted with pliers.:@

I had to carefully nip the collar off so I could push them into the wall and then install new ones in the same hole. Also, remember that there are plugs for both single and double gypsum.

And you should drill with the right drill bit, usually 10.5 mm, so that the board doesn't split on the inside when you insert the plug.

A tip is to use duomax instead of molly. Then no tools are needed.

 

[Hubbe2]

And you should drill with the right drill, usually 10.5 mm, so that the board doesn't split on the inside when you press in the plug.

Correct, however, the drill dimension depends on which screw is used. They are normally in M4, M5, and M6.

ceson: They are available for single, double, and triple gypsum.

ceson: They exist for single, double, and triple gips.
