Good day, dear guests and subscribers of my channel!
On this page, I will look at the most common plastic expansion plugs for screwing in screws, to attach a shelf to a vertical wall, hang a cabinet or any equipment, and to the ceiling - a chandelier, cornice and etc. Such products are intended for a very wide range of tasks in construction and decoration and the most popular in the household life of the owner of the house are diameters from 5 mm. up to 10 mm., the rest are used much less often.
The dowel is an auxiliary element that ensures reliable fixation of the screw in the base (in the wall, in the ceiling) due to the expansion inside the hole.
In the article, I will not touch on special-purpose dowels, like these:
And I will consider the most often used options for full-bodied structures:
The market offers a very wide assortment and it would seem that there is a dowel and a dowel, but 90% of buyers do not see the difference between them. In fact - each product is designed for its own tasks.
The fact is that in the structure of the dowel there are subtle design features that greatly affect its functionality, which I will talk about later, comparing several types and identifying the advantages and disadvantages everyone.
Consider 3 types:
1. White
So, the simplest one is white two-petal:
Usually, it comes with a mounting kit with any product. It is the cheapest and most ineffective, so I always throw it away. Both petals, when spread, do not provide reliable fixation. The plastic is hard, the grip is weak, so it easily slips in the walls of the hole. With a little effort, the fastener pops out. Often - at the moment the screw is screwed in - it turns.
Conclusion: Such a dowel is capable of cutting only, i.e. only within the walls. Ceiling mounting is unacceptable, as it does not resist being pulled out well!
2. Blue
The next type is a blue spacer with spikes:
There are two- and three-lobed. Due to the spikes and soft material - it perfectly provides grip inside the hole, moreover, it is slightly deformed, which gives a guarantee for reliable fixation. But, again, if the drill / drill, while drilling / drilling a hole, slightly gouged the plaster, then such a dowel will turn when screwing a screw into it.
Conclusion: The dowel is good, it is applicable for installation both in walls and ceilings. But, not immune to cranking. With good effort and dynamic pulling attempts, it still comes out of the hole.
3. Orange
And finally, my favorite is the "carrot" dowel.
This is one of the versatile types that works both as a spacer and as an anchor element. For a full-bodied material - it creates a thrust, trying to tie into a knot, for a hollow material - it ties into a knot:
There are many such varieties, but "carrot" (named for its color) is the most popular. We can apply it everywhere, as it works great for both pulling and cutting. At the base it has protrusions that, when the dowel is driven in, repeat the geometry of the hole, due to which it does not turn. Braided into a knot, it sits securely even in drywall.
To correctly apply such an element, you need to pay attention that the screw is slightly longer than the dowel itself.
Disadvantages:
- The diameter is less than 6 mm. - can not be.
- Disposable. The deformation is so strong that it cannot be reapplied by pulling it out of the hole.
Important advice
Before hammering in any plastic dowel, always empty the hole of the drill meal. Otherwise, these particles do not allow the dowel to be securely fixed in the hole and create a slipping effect.
I really hope that this article was useful to you.
Thanks for attention!
