Bottom bolt DIN 609
Due to the peculiarities of its structure and use, the DIN 609 socket bolt is also called a hexagonal tightening bolt with an incomplete thread, the main purpose of which is to fasten fasteners of high strength, precision and reliability. Another distinctive feature of this product is that the thread pitch can be customized to the customer’s needs, which significantly increases the scope of its application.
Most often, bolts of this configuration are used in industrial production, machine tool building, construction, instrumentation as a connector for threaded parts, and even mechanical engineering, wherever there is a need for a high-precision mechanical connection.
Taking into account the characteristics of this product (steel strength class 8.8\10.9, galvanization, small journal, screw design, etc.), we get a connection that makes it absolutely impossible to unscrew under any even strong vibrations or dynamic impact, which in turn provides us with the highest reliability. degree of connection of individual elements of any structure. In addition, this metal product is successfully used in machine tools with moving parts complete with bearings, and the high-quality and high-strength steel of the product ensures a very long service life.
Based on customer feedback, we recommend that you buy the DIN 609 socket bolt with a washer, nut and engraver, which will help you achieve greater tightening and stronger hold in the most difficult joints.
