How to Screw to Walls Avoiding Breakage?
On reflection, it is all well and good to make your own shelves, your own storage compartment etc ...
The point is, once the product is finished, you have to fix it well and this is where things go wrong.
To avoid injury and to extend the life of our latest creations, it is useful to know how to screw them to the walls while avoiding breakage !!
Go home to find your broken flat screen right in the middle of the living room is something we would all like to avoid.
Likewise, we do not generally like our furniture to fall on our heads or on that of our children !!
So how can we be sure that this will not happen to us or no longer?
Which screws to choose?
Obviously the choice of screws will be different depending on the object you want to fix, its weight and thickness and the quality of the wall.
Remember that any competent seller will be able to advise us in the DIY department depending on the type of wall in which we want to fix!
the screw diameter will therefore depend more on object weight to fix and its length than the quality of the wall.
In general, for us Sunday DIY enthusiasts, 3 mm screws are sufficient for light objects (frames, shelves of less than a kilo when loaded, etc ...), 5 mm screws can support your furniture. light kitchen, 6 mm for the heaviest, that can climb up to 16 mm threaded rods for a gate or other extremely heavy objects.
It may be necessary to choose larger screws in the case where:
1.they would withstand traction on their axis (chandelier)
2. the density of the wall would be poor.
The length of the screw will rather depend on the quality of the wall and the thickness of the object to be fixed: any screw is only effective without the plug that goes with it as part of a fixing in a wall.
So, whatever the thickness of the object, the screw will have to arrive deep in the ankle. It is therefore necessary to plan the useful length of the screw (the one that will be in the wall) taking into account the length that will exceed.
Ankles: which ankles?
There are many types of ankles and all of them have their own particularities. Likewise, thee seller of our DIY department preferred will be able to advise us between the different kinds:
- the standard anchor: for almost all materials, except cellular concrete, plasterboard and chipboard panels.
- the universal anchor: made of metal or plastic, it is suitable for most solid and hollow materials except cellular concrete.
- the hollow brick anchor: it can also be used for plaster blocks.
- the anchor for cellular concrete: it is only suitable for this material.
- the plasterboard anchor: made of metal or plastic, it is suitable for 4 mm wood screws and only supports light loads.
- the expansion anchor: made of metal, it requires a clamp intended for its use and supports weights greater than its plastic cousin. They are intended for plaster, chipboard panels, hollow concrete blocks ...
- the quick-fixing anchor: it is designed for light loads. Very easy to use, it only adapts to concrete and solid concrete blocks.
Here is the list of the anchors that we will need the most; note that their formats vary as much as that of our screws, so we must match the measurements of both.
More than to screw!
Once the screws and plugs have been chosen, all I have to do is drill holes of the same diameter in my wall, equip myself with a hammer to drive in the plugs and of course a screwdriver or a electric screwdriver !
Your turn...
