    Abstract. Fasteners play an important role in modern construction. These include post-installed anchors, which are installed in a hole drilled in the finished structure and used to fasten building materials, products, structures and equipment. They are often used as an alternative solution to the use of embedded parts. Advantages and disadvantages of anchors are revealed both from the point of view of calculation and design, and installation. Classification of anchors is presented. It is shown that chemical (adhesive) anchors, which are a system of adhesive composition and a steel element, are very promising. This type of fastener has the greatest flexibility of design solutions. It is established that chemical anchors have a more complex set of operational parameters in comparison with mechanical ones. With this in mind, the article also reviews the regulatory documentation developed in recent years in the field of laboratory testing, calculation and design of anchor fasteners, in particular, the analysis of the features of adhesive anchors and their main properties. The bearing capacity is significantly affected by the operating temperature, the method of drilling the hole, the type of element to be glued, the minimum permissible installation temperature, etc. The features of the composition and properties of slow-and fast-hardening chemical anchors are analyzed. It is noted that "winter" adhesive compositions with low installation and operation temperatures and high rates of strength gain at negative temperatures can become a very promising and relevant field of research for our country.
    Key word: anchor, main types of anchors: post-installed, chemical, bonded, mechanical, anchorage, anchors in concrete, anchors in brick masonry.
