No renovation or construction job is complete without high quality fastening systems. New technologies have not bypassed the construction industry either; reliable fasteners have appeared. The article will discuss one of them - a nylon dowel.

Peculiarities

Dowel - a sleeve made of any material with ribs located on the outside of the product for reliable fixation and prevention of rotation during operation.

The main distinguishing feature of the nylon plug is a longer service life . It can last more than 10 times longer than polyethylene. They have been in operation in European countries for more than half a century. They are made of a special material - polyamide, which does not age over time and does not shrink. These properties of this type of plastic make it possible to use nylon plugs for many years without fear of their reliability.

Another feature is pretty wide temperature range , at which such fasteners can be used - it is from –40 to +80 degrees Celsius. It should be noted that it can be used at lower temperatures at your own peril and risk: deformation and rupture may occur, or the dowel will not fully enter into place. But, as practice has shown, it will still hold better than ordinary polyethylene.

Due to the high degree of strength and reliability, this type of fastener is able to withstand loads about 3 times higher than the fastening rods made of simple plastic. The only drawback compared to the rest is the higher cost due to the fact that a higher quality type of plastic is used.

Nylon fasteners have another interesting feature: when placed in water, they will sink, unlike their other plastic counterparts.

The fact is that the material from which they are made is denser and heavier.

Appointment

Plastic nylon plugs are designed for use in almost any humidity conditions indoors or outdoors. The range of their application is quite wide:

• when installing door and window openings;
• if you need to fix lighting or plumbing fixtures;
• with its help mirrors are attached;
• it is used in electrical installations;
• when installing and installing plumbing, ventilation and air conditioning systems, you cannot do without nylon fasteners.

Varieties and sizes

Engineering thought does not stand still, and during the operation of nylon fastening rods, many types have been developed for various tasks and purposes. Let's consider the main options.

Usual … The main area of its use is internal work. It is used when working with bricks (ordinary and ceramic), gypsum and other materials, in general, where the load on it is insignificant.

Ordinary screws can also be used for fixing.

With cuff . The board is used in cases where the load on the dowel is up to 100 kg. It has special hooks on the cone, which allow it to withstand various mechanical influences.

This is probably the most common and popular type among DIYers who specialize in home repairs.

Elongated . This type has a more elongated part, with the help of which it is securely attached to the material. For this fastener, special elements have been developed that securely fix it. They resemble shark teeth, which, when the cylinder is expanded with a self-tapping screw, effectively press on the walls of the hole - thanks to this, reliability increases many times over.

Universal … It has a special design and a tear-off cuff. Therefore, it can be used in solid and hollow materials. Removable collar allows for flush mounting and through holes.

Dowel nail . As the name implies, it can not only be screwed in, but also hammered if necessary. Available with three different cuffs - concealed, wide and cylindrical. This type of fastener has a more durable head and base at the neck of the self-tapping screw, an increased opening zone - all this allows it to withstand higher loads and protects against unwanted consequences in the form of kinks.

And also it is equipped with a special thread that allows you to remove it from the recess or make adjustments.

You can find dowels of the following specific types: facade, for scaffolding, for hollow bricks and many others.

The most common nylon plugs have these parameters - 6x30, 6x40, 8x60, 8x40, 10x50, 6x60 mm . These sizes are considered standard, there are also elongated ones.

This type of fastener products is manufactured according to European DIN standards.

What is better than polypropylene?

Basically, the characteristics of nylon and polypropylene dowels are similar .… But the first one is more resistant to shocks and other mechanical influences and, unlike polypropylene, it lasts much longer and does not crack over time. And also it is more frost-resistant and does not absorb odors.

In general, nylon dowels are more preferable for all types of indoor and outdoor work than others, but their higher price and hygroscopicity should be taken into account.

Since they absorb water, it is better to mount them outdoors at a time when there is no rain or high humidity.

Selection options

To choose the right nylon dowel, you need to know:

• the load that he will experience;
• the type of material in which it will be embedded;
• the depth and diameter of the hole.

Then you need to pick up a screw for fixing. A regular self-tapping screw is perfect.

But if it is assumed that the humidity will be increased, then it is better to use galvanized hardware.

Mounting

Installing these tie rods is simple and no different from the rest

• First you need to make the markup.
• Then, using a tool - this can be a hammer drill or an impact drill - drill the hole to the desired size.
• The next step is to clean the groove from debris and dust. After that, we install the dowel and screw in a self-tapping screw of suitable length and diameter.

There are now a large number of various domestic and foreign manufacturers on the market, so choosing the right dowels is not difficult.
