In addition to choosing the right plugs, it is also important that you combine the right screws with the chosen plug. In our blog which plug size goes with which screws, we clearly indicate which screw sizes belong to which plug sizes.

Nylon plugs

In the table below you can read which screw size belongs to which plug size for our nylon plugs. In addition, the maximum pulling force, how thick you should pre-drill, and how deep you drill are also displayed.

Which Plug Should I Choose?

In order to arrive at the right answer, it is important that you find out whether you are dealing with a hollow wall or a solid wall/ ceiling. A plasterboard wall would be an example of a hollow wall. A solid wall is one made of stone, concrete, or plaster blocks. For hollow walls, use hollow wall plugs. And with solid walls, you can use hammer plugs or nylon plugs.

Do you always want to have the right plugs? Then take our universal plugs. These are suitable for both solid walls and hollow walls. This is because the plug changes into a prop when the screw is screwed in.

Hollow Wall Plugs

With a hollow wall, you can use our hollow wall plugs. You can recognize a hollow wall plug by its unique shape. With a hollow wall plug, which is also called an umbrella plug, the rear part expands when the screw is screwed in. The image below shows how this works.

How do I Install a Nylon Hollow Wall Plug?

First, you drill a hole in the hollow wall. Pre-drill the hollow wall plugs with a drill bit that is 2 mm thicker than the thickness of the plug. With hollow wall plugs 8 x 40 mm you, therefore, use a 10 mm thick drill. Press the flaps of the hollow wall plug together and insert them through the pre-drilled hole. Now tighten the screw in the plug. The screw ensures that the plug is clamped in place. If you opt for hollow wall plugs without screws, you must order the screws yourself. For 8 mm thick hollow wall plugs, choose 3.5 mm thick full-thread screws.

How do I Install a Metal Hollow Wall Plug?

The mounting of metal hollow wall plugs is actually done in the same way as the hollow wall plugs made of nylon. However, with metal hollow wall plugs you have the choice to do it in 2 ways. Namely with or without pliers, for hollow wall plugs.

Installing Metal Hollow Wall Plugs with Pliers

The installation of metal hollow wall plugs with pliers is done as follows: First, you drill a hole. Then loosen the screw slightly from the plug so that you can slide the head of the screw into the groove of the pliers. Then tighten the plug slightly so that it slightly clamps on the pliers. Push the plug through the hole and squeeze the pliers. The back of the plug is now pulled towards the hollow wall. As a result, the plug expands like an umbrella, so that it clamps to the plasterboard wall. Because of this, these plugs are also called plasterboard plugs.

Installing Metal Hollow Wall Plugs without Pliers

Mounting a metal hollow wall plug without pliers is actually the same as mounting a 'normal' plug. First, you drill a hole and push the plug through the hole. Carefully, clamp the plug into the plaster mitt with a hammer. Then, unscrew the screw from the plug and place the material to be hung. If you put the screw back into the plug and tighten it slightly, the back of the plug will expand like an umbrella. As a result, the plug clamps itself firmly to the hollow plaster wall.

Impact Plugs and Frame Plugs

You need hammer plugs or frame plugs when you want to fix a wooden beam or sheet material in a stone or concrete wall. The advantage of these plugs is that you hold the material in the desired location on the wall and drill a hole in one go. Then push the hammer plug or frame plug into the hole and hammer it in with a hammer. In this way, you can quickly anchor materials to a stone wall. The material is now firmly attached to the wall or ceiling. Watch the video below for an additional explanation about mounting a beam to the wall. Frame plugs are used for this. These have the same effect as hammer plugs, only they are longer and thicker. This gives them more carrying capacity.

Plasterboard Plugs

These plasterboard plugs are only suitable for plasterboard walls and you can drill directly into the wall. Thanks to the self-drilling tip, pre-drilling is not necessary. For the best end result, however, small pre-drilling is recommended. You then ensure that the collar of the screw is flush with the plasterboard. If you do not want to pre-drill, you should screw in the plasterboard plug until the head is flush with the plaster wall.

A big difference compared to other plugs is that the shape of these plasterboard plugs does not change when the screw is screwed in. Where other plugs expand, attract or change into a prop, this plasterboard plug remains the same. A disadvantage of these plasterboard plugs is that they leave a large hole after you want to remove the plug again. A big advantage is that these plugs are very strong and have a lot of bearing capacity.

Universal Plugs

The Universal Plug, as the name suggests, is suitable for universal use. This means that the plug can be used for both solid walls, like concrete and stone, and for hollow walls, like plaster walls or hollow brick walls.

The plug is universal because it changes into a kind of prop when the screw is screwed in.
