Fasteners for wooden structures provide reliable fixation at the joints of wooden elements. These parts make it possible to obtain a durable structure that can withstand various vibrations and mechanical loads.
Various types of wood fasteners differ in size and purpose. They have an unusual shape and structure.
How to choose the right metal products that will help create a durable building? The answer to this question is presented in our detailed material.
Types of fasteners for wood
The following types of connecting elements for wood are distinguished. These include:
- connections with perforated base;
- anchor screws;
- "tenon and groove";
- three-dimensional slats;
- "hedgehog";
- self-tapping screws with KonstruX thread.
Each type of product differs in size, shape and material from which it is made.
Perforated connections
This type of connection is used for fixing wooden and concrete parts. Most often they are hidden deep in the cavity of the structure being built. They are made from durable hardened steel. The thickness of each element ranges from 1.6 to 2.5 mm.
In specialized departments there are products made of low-carbon steel. As a rule, such models have a fairly high cost. They are considered stronger and more resilient.
They are mainly used when laying ceilings and floors. Such hidden fasteners for wood can be used in the construction of houses made of timber.
Types of corners
All angles for fastening beams according to the type of cross section are divided into two main groups: equal-flange and unequal-flange. The photo below shows both of these types.
With an equal-flange mount, both sides are the same length. If, for example, a product is marked 50*50, this means that each side is 50 mm long.
The range of produced equal-flange fasteners is quite wide and is regulated by GOST 8509-93. According to the standards defined in the document, the product labeling must also contain an indication of the accuracy of the rolled product. High-precision rolled products are designated by the letter A, standard-precision rolled products are designated by the letter B. An angle for attaching timber with markings A will allow you to create a perfectly accurate angle, while marking B indicates a less accurate correspondence to the right angle and greater strength of the product.
The production of an assortment of unequal-flange fasteners is provided for by GOST 8510-93. This mount has two different shelves, their length is indicated in the marking. In addition, products also have designations depending on the rolling accuracy (A and B).
An equal corner is used to fasten beams together in those places where it is necessary to create even corners. Using them, openings for windows and doors are formed, and slopes are installed. Equal-flange fasteners are also used to assemble frames from 100*100 timber.
Unequal-flange fastening is suitable for forming non-standard angles during the installation of rafters and the construction of the supporting structure of the roof.
Metal anchors
Anchor screws have huge advantages among most products. They can be used in conjunction with perforated connections. This ratio makes it possible to make the building resistant to climatic disasters.
These products are made from high-strength metal alloys. Most often they are re-hardened and plated with zinc. Galvanized wood fasteners can be used in areas with high humidity. They are resistant to corrosion and deformation during the driving process.
The length of the elements varies from 5 to 10 cm. The diameter is about 6 mm. Such models are used to create roofing or flooring. There is a screw thread along the entire length, which ensures tight fixation inside the wood.
Tongue and groove system
This variety is produced by a German company. The product is made of durable aluminum alloy. One part has spikes, and the other is equipped with an additional groove. They are installed according to the dovetail principle. Thanks to this connection, it is possible to reduce the load on the building during operation.
A similar model can be used for both hidden and closed connection points. It is recommended to install metal parts in pre-prepared holes. They should be firmly attached inside the wooden base.
The main disadvantage of this model is their high cost. This is directly related to the complexity of the structure and its reliable fixation of wooden parts.
Fastening to columns
Columns are installed over long spans to relieve the load on the beams and prevent them from sagging. They are attached to columns using a supporting or hanging method. But often the support area is insufficient for laying and joining two beams, and it needs to be increased.
- Bolts of sufficient cross-section are screwed onto the wooden pole with wood grouse on the sides.
- A support platform made of thick sheet steel is welded onto the metal one on top.

3D slats
Specialized departments provide a detailed catalog of the best wooden fasteners. One of these connections is three-dimensional slats. They are connected perpendicular to each other. As a result, a T-shaped connection is formed, which is considered the strongest.
They are made from durable metal alloys that can withstand all kinds of loads. They have a length from 60 to 750 mm. There are cuts and protrusions along the entire plane of the iron model.

During the installation process, one edge of the part is fixed in one of the parts of the wooden beam. Next, small cuts are made on the logs, equal in length to the protruding part of the three-dimensional lath.
The choice of such a product should be made in accordance with further loads during operation.
Terms of cooperation
In our company, we offer to buy metal fasteners wholesale and retail for individuals, individual entrepreneurs and commercial organizations of all forms of ownership; we are interested in long-term cooperation. We maintain long-standing partnerships with leading manufacturers of metal fasteners; product prices are affordable, without intermediary markups.
The catalog contains fastenings for wooden structures between each other and to various bases, as well as mounting elements for communication systems. Delivery of goods is organized, any types of payments are acceptable.
Products "Hedgehog"
They are a large washer made of low carbon steel. Galvanic coating is applied along the entire perimeter. They are designed for self-tapping screws. The diameter of the washer is from 50 to 85 mm.
There is a small recess in the upper part, drilled at different angles. This provides different connection depths during the installation of wooden parts.
