Review
GOST 22353-77 High-strength structural bolts are a type of fasteners that are used to connect elements of responsible structures and allow to ensure the stability of the nodes of these structures to loads. Such bolts are special fastening elements designed for use in connections subject to vibrations or high dynamic loads.
Strength class GOST 22353-77
Bolt strength class GOST 22353-77 is the maximum applied force, when applied, the bolt begins to break. GOST 22353-77 bolts are manufactured in strength class 10.9.
High-strength GOST 22353-77 should be bought only from verified suppliers. It is made of alloy steel and such bolts are used for responsible projects where, in addition to high loads and static loads, the din 6914 bolt is subject to constant vibration. Such bolts will be especially relevant in bridge construction, instrument construction, as well as in structures located near objects subject to vibration.
Fastening group GOST 22353-77
High-strength bolts are made only from high-strength steel and belong to the High-strength fastener group.
Materials for the manufacture of bolts GOST 22353-77
High-strength bolts are made only from high-strength structural alloy steel. The high strength class 10.9 allows the use of bolts in highly loaded connections.
Scope of use of GOST 22353-77 bolts
The products are intended for operation under conditions of increased loads. Steel with strength class not lower than 10.9, with zinc coating, is used for production. The main field of application is highly loaded prestressed threaded connections in steel structures. Fittings are supplied with a thread diameter from M12 to M36. Tightening requires great effort, which is achieved due to the increased head, but the use of GOST 22353-77 bolts does not require special skills and equipment.
