Overview
ISO 7412 High-strength structural bolts are a type of fasteners used to connect elements of responsible structures and allow to ensure the resistance 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 ISO 7412
Bolt strength class ISO 7412 is the maximum applied force at which the bolt begins to break. Din 6914 bolts are manufactured in strength class 10.9.
High-strength ISO 7412 should only be purchased from proven 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 ISO 7412 bolt is subjected 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 ISO 7412
High-strength bolts are made only of high-strength steel and belong to the High-strength fastener group.
Materials for making bolts ISO 7412
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.
Field of application of ISO 7412 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 a lot of effort, which is achieved due to the enlarged head, but the use of ISO 7412 bolts does not require special skills and equipment.
