Convenient slot	For tightening self-tapping screws, the PH2 nozzle is used - the most common and popular. Almost everyone has such a screwdriver, you do not have to look for some special tool

Wide range of sizes.With a thickness of 4.2 mm, the length of the products can be from 13 to 76 mm. You can choose the best option for any conditions;

The length is selected depending on the thickness of the bars and the weight of the corrugated board

The sharp tip is not only perfectly screwed into the tree, but also pierces the profiled sheet without any problems. You do not need to additionally drill the surface, which is very convenient;
This type of product is used when fastening corrugated board to a wooden bar. Most often, such self-tapping screws are used in the construction of fences and sheathing with profiled sheets of walls;

This option is good when fastening to wooden logs.

The price of fasteners is most often calculated for 1000 pieces and, depending on the length, can range from 900 to 2000 rubles.

Option 2 - fasteners with a press washer for metal

This is what it looks like in the drawing

These are self-tapping screws for attaching corrugated board to metal. Their main difference from the above option is the presence of a drill tip, thanks to which fasteners can be screwed into metal 2 mm thick without pre-drilling.

This option has the following features:

The length can be from 13 to 75 mm, while the diameter remains unchanged - 4.2 mm;

Long options are good for fastening to metal hollow structures

Fasteners can be screwed into metal up to 2.5 mm thick without prior preparation. If the wall thickness of the metal is greater, then it is necessary to pre-drill holes. A drill with a diameter of 3.5-3.8 mm is used;

If the base metal is thick, then holes are pre-drilled

The cost for 1000 pieces is from 1000 to 2500 rubles, depending on the length and manufacturer;
Fasteners are suitable for mounting fences, awnings and other structures on a metal frame.

Option 3 - painted self-tapping screws with a press washer

The two options described above have a significant drawback - galvanized elements stand out against the background of the material and spoil the appearance of the surface. Therefore, manufacturers began to produce a variant in which the heads are painted in different colors according to the RAL marking.

Let's analyze the main features of this solution:

Fasteners can be both with a drill and with a sharp tip, which allows you to choose an option for any base;
Each manufacturer offers an assortment of two dozen colors, which in their shades coincide with the color of the corrugated board.. You need to know the color marking of the base material, and you can easily select fasteners for it;

Most often sold options with a drill tip

The cost of the elements is almost the same as that of the galvanized options, a thousand pieces will cost only 200-300 rubles more.

The most important advantage of this type of product is that, due to the color matching with the surface and the flat shape of the cap, the fasteners are almost invisible. This allows you to get the perfect look of a fence or other structure.

Colored flat hats are almost invisible on the surface

Option 4 - wood roofing screw

This type of product differs from the above in a number of ways:

This self-tapping screw for corrugated board has a hexagonal head for M8 nozzle. This allows you to twist the elements even into hard wood without problems, because the head will withstand even heavy loads;

When working, be sure to use a special nozzle for a screwdriver with a size of 8 mm

Washer with rubber lining allows for a snug fit to the surface without damaging the profiled sheet. In addition, this element protects the hole from moisture penetration, thereby extending the life of the structure;

Rubber gasket under the washer helps protect the attachment point from moisture

The dimensions of the products are as follows: the length can be from 29 to 80 mm, and the standard diameter is 4.8 mm;

Here is all the data for this product group

Hats in self-tapping screws can be both colored and galvanized. The first option is in much greater demand, and this is understandable, because the profiled sheet is always colored;

The cost for 1000 pieces starts from 1200 rubles and depends on the length and manufacturer;
The drill tip eliminates the need to drill the profiled sheet before fastening and makes it easier to screw the fastener into the wood.

The drill tip can easily pass through metal up to 1 mm thick

Such fasteners can be used both on the fence and when attaching a profiled sheet to the rafter system. The main thing is to choose the optimal length for each case.

Fastening to a wooden truss system is made with just such fasteners

Option 5 - metal roofing screw

If you need to fix the sheets on a metal frame, then you will need this particular type of product.

Its features are:

This type of product has a drill size much larger than the previous one.

The drill allows you to screw fasteners into sheets up to 3 mm thick without additional drilling. This simplifies the job;
The thickness of the fastener is 5.5 mm, which increases the strength of the structure;
The length can be from 19 to 50 mm. But short options are in the greatest demand, since it is convenient for them to screw the material to posts and profiled pipes.;

A large drill allows you to quickly attach the material to the metal

The fastener is equipped with an 8 mm hex head, for which a special nozzle is purchased;
Screwing is done through a wave of a profiler so that the self-tapping screw does not travel on the surface, it is better to make marks with a core in advance;

A mark is made with a core, after which it will be easy to screw in the screw

The cost of this type of product is from 2000 per 1000 pieces.

Option 6 - Roof fastener with oversized drill

These self-tapping screws for profiled sheets are the most durable

This type of product has the following features:

If you need to fix the material on metal surfaces with a thickness of 5 mm or even more with your own hands, then this option will allow you to do it quickly and efficiently;
A long drill is able to pass through metal up to 10 mm thick without pre-drilling. The main thing is to take a more powerful drill;

A long drill will cope with the most difficult task

The diameter is 5.5 mm, and the length can be from 25 to 102 mm. You can choose the optimal configuration for any task;

Fine thread allows you to securely fix the screw in the metal

It should be remembered that self-tapping screws with an enlarged drill are only available in a galvanized version. You will not find colored products of this type. That is why these elements are most often used in industrial construction and on roofs.
