Suitable screws and wall plugs?

dhokes

I'm a relative beginner when it comes to DIY and I attached some coat hooks to a wall with the screws/wall plugs that arrived with the hooks however it fell off! I'm guessing I should use longer screws. The coat hook is made of a piece of wood and the wall is solid.

I was wondering if the screws in this image are suitable or would you suggest only using masonary?

The screws have the following dimensions:

Diameter = 5mm

Inner thread diameter = 3mm

Length = 60mm

Screw head diameter = 10mm

I'm slightly confused as to what the numbers on the wall plugs refer to and which should I use for the screws?

The screws need to go beyond the end of the plugs so forcing them open to grip the wall. From your picture the screws are too short probably because the wood is relatively thick. Try 70mm long screws.

You say the wall is solid, do you know what material or can you post a close up of the holes?

Its a 5 year old new build property but not with thin hollow walls, its got solid internal walls.

It might have AAC blocks on the inner skin. Was it really easy to drill into?

It was fairly easy up until around 4cm if I remember correctly and then it was hitting something more solid.

Longer screws are required - I usually aim for 30mm to go in to the wall. So that would be 30mm plus how ever thick the bit of wood is.

One tip - Tap the wall plugs in about 12mm below the surface of the plaster. This will ensure the plugs are expanding into something solid rather than plaster. Plaster does not have much strength to it and will crumble. Sometimes, I'll put a squirt of grab adhesive in the hole before inserting the plug.. Or if I really need a strong grip, a resin fix.

Did you use the right size of drill bit?

The 4 holes in the center of your picture are guides to the size of drill bit that you can be used but the tighter better. if  you have used the correct size of bit change screws to 70mm or 80mm

How can I tap the wall plug in further btw if the wall plug is a tight fit to the hole + I hammer it in so that its flush to the wall?

I use an old screw with a head about the size of the plug, then hold it backwards and gently hammer the plug further into the wall to get the plug below the plaster surface. Needs the hole to be deep enough of course!
Also means when you remove the screw and whatever it was holding, you can just fill the hole without trying to pull the plug out and a lump of surrounding plaster with it.

I would put the wall plugs into the wall, then tap level.

Then put nice long screws screw through the bit of wood, and give a couple of twists with fingers to get them seated in the plugs.

Then gives the screws  a tap with the hammer to get the plugs below the plaster.

Then tighten.

Make sure the holes are deep enough. I always drill far too deep, but…
