How to choose window screws?

When installing the window does not do self-tapping screws. These elements provide a durable and reliable connection of the frame with the base. The modern market offers a huge variety of self-tapping screws with different performance characteristics and features. Properly selected screw is the key to practical and strong adhesion of structural elements.

The experts have compiled a list of aspects that indicate that the screw is intended for fastening window systems, namely:

• there are special notches on the head on the side of the fastener thread;

• special shape of the head.After fully screwing in, it does not protrude under the base, providing a neat appearance;

• strong adhesion between the tool and the screw in the process of screwing, which is provided by the cross-shaped slots under the screwdriver.

In the segment of window screws includes several types of products. Each option is used to achieve a specific goal. To make the right choice, you need to know exactly the difference between the models.

This variety is the most common and widely used. The window screw of this type has a number of advantages. It is necessary to identify the advantages and features of the use of screws.

• Head shape. Head dimensions are 7 mm. The element has an original configuration, due to which the fastener is completely screwed into the surface, even if it is screwed unevenly. The form greatly simplifies the work.
• Versatility. Self-tapping screws can be safely used to install not only PVC windows, but also wooden structures and sheet-type materials. The function is possible due to the wide thread. As well as fasteners suitable for mounting structures on soft bases.

• Electroplated coating. In the manufacture of manufacturers put a layer of gold or silver zinc. The coating protects the metal from the damaging effects of the environment, mechanical stress and loads. Due to the zinc layer, the screws are able to withstand high temperatures, up to 150 degrees Celsius with a plus sign. If the screw is made in accordance with high quality standards, then its entire surface will be galvanized.
• Wide thread pitch. Thanks to this characteristic, the process of screwing fasteners is significantly accelerated. The sharp tip reliably fixes the self-tapping screw on the basis and does not slide in operating time. Even a novice without experience will cope with the task.
• Large selection of sizes. The thickness of the window fasteners of this type does not change and is 4.1 mm, but the length may be different. The wide size range allows you to choose the best option depending on the size of the structure, the hardness of the material and other factors. Standard length is 1.9; 2.2; 2.5; 3.0; 3.5; 3.8; 4.5 cm

This segment is very similar with the above group, but there are some differences that you should pay attention to, such as:

• The main purpose of the screws is the coupling of the fittings with other structural elements in the event that when introducing standard screws a thread was broken. Manufacturers have increased the size of fasteners. Their diameter is 4.8 mm, so that the screw is held securely in the hole;

• larger sizes played an important role in durability and reliability.

• as in the case of the previous group, the screws are equipped with sharp tips, which provide quick and easy screwing in;

• head diameter is 7 mm. High-quality and dense embedding is ensured by a semi-circular top;

• for strong fixation on the bottom of the head are the ribs.

This type has a number of features that distinguish it from other window screws.

• Drill. Screws with a drill are suitable for working with metal profiles. A sharp element is placed at the end of each screw. Fastenings are ideal for fixing fittings, fixing parts on the reinforcing profile, as well as fastening structures.
• Notches. For convenient use of the self-cutting screw on a hat there are notches. Even when using a tool with a coarse torque adjustment, reliable fixation is guaranteed.
• Using. Experts do not recommend the use of such screws when working with wood due to the fine thread pitch and drill bit. The thickness of the screw is 3.9 mm with a length of 1.3 to 3.8 cm.

This type is also called self-tapping. They are used in various fields, including the construction segment. When installing PVC double-glazed windows, they are also common. These products have a number of features.

• Dimensions. Screw thickness varies from 4.2 to 6.3 mm. Length - from 13 to 70 mm. The wide size range allows you to choose the ideal option depending on the density of the base, size and other aspects.

• The hat. Due to the round cap with a flat base, it is very easy to press and fasten flat parts. Despite this characteristic, the element is not fully embedded in the base. It is recommended to use screws in the event that the convex cap does not cause inconvenience.
• Mount. This type is actively used in the process of assembling window constructions. Given the extensive size range, it is easy to choose screws for a specific purpose. Short models are great for installing roller (Roman) curtains, and long ones are better to use for roller shutter systems and other elements.
• Coating. Screws are covered with a layer of zinc to protect against negative environmental factors.

Fasteners of this type are used in many areas, the installation of PVC windows is no exception. Specialists have made a number of advantages of screws with a press washer.

• Versatility. For fasteners there are applications in various fields.

• Dimensions. Despite the constant thickness of the elements, which has 4.2 mm, length varies from 13 to 75 mm.

• Convenience. The standard PH2 nozzle is ideal for working with screws. Working with these elements is simple and easy.
• Appearance. Both galvanized and color screws are available for customers to choose from, which is an important factor from an aesthetic point of view.The cost of products in color is higher compared to the standard, but the difference is minimal.
• Practicality. Fasteners are ideal for working with sheet materials. Under the cap of the screw is pressed on the washer. Due to this, the diameter of the pressing part reaches 1.1 cm.
• The form. Screws with drill bits and sharp hardware are available. The first option is used when attaching metal elements with a thickness of up to 2 mm.

This type of window screws is also called Nagel or turbosurup. The segment has significant differences from the above groups. Initially, manufacturers made screws to fasten door and window frames to concrete or brick foundations. However, many experts claim that they can be safely used to fix structures to the tree. And also screws for a long time will fasten PVC products among themselves.

Self-tapping screws differ in large dimensions. Their length ranges from 52 to 202 mm, with a thickness of 7.5 mm. For the twisting of elements is used a nozzle in the form of a star (marking - Torx T30). In some cases, the PH3 crosspiece is suitable. Most often, screws are used for mounting windows without slopes.And also they can replace the standard window anchors, for the introduction of which a preliminary opening is being prepared. This is a practical choice for weak bases that can be damaged when the anchor is tightened.

The self-tapping screw with a drill in the size of 3,9х19 mm is the most widespread option during the work with metal elements of a window profile. A durable element with a drill freely passes through a solid and dense material. For the manufacture of fasteners used carbon steel. To improve anti-corrosion properties, galvanizing is carried out galvanizing. The use of a 3.9x19 mm screw does not need to be pre-punched.
