Threaded stud: basic concepts and applications

The threaded stud is a fastening element that is widely used in construction, mechanical engineering, furniture and automotive industry, in repair work and other industries. This fastener is designed for building various structures and connecting parts, Located at a great distance.

The threaded galvanized threaded rod is a metal rod (rod), along the entire length of which is metathed by the rolling method . In view of the fact that the hairpin is often used in conditions of various temperature changes and high humidity, it is zinc treated or made of stainless steel. A bare-end threaded rod (black) is operated under more gentle conditions, where an aggressive environment can not cause corrosion of the metal.

The size of the studs and the construction are strictly standardized. Material of manufacture, accuracy class, main dimensions, conditions of transportation and storage, as well as possible deviations from regulatory rules are regulated by the standard DIN975. The size of the studs is determined by the total length and diameter. They are meter, two-meter and three-meter, the diameter varies from M3 to M42. Threaded stud is used with all fasteners of imported production. With its help, the following tasks are solved:

• Fixing suspended ceilings, frames, cable boxes and other devices;
• Installation of heating and ventilation systems;
• Construction of frame houses;
• Connection of elements of wooden logs, boards and beams;
• Formwork manufacturing while working with concrete;
• Installation of billboards ;
• Adhesion of materials during finishing, roofing or repair work;
• Installation of ceilings, plasterboard partitions;
• Other general construction works.

Most often, the threaded stud is mounted with clogged anchor fasteners, metric nuts and washers, connecting bushings and a perforated profile of different lengths. Sometimes it is used as a fixing or tightening element in the assembly of the formwork or acts as a suspension. Length The threaded rod can be cut by cutting to the desired size. In addition, it can be used in the construction of foundation anchor bolts as a component - for mounting a metal sub-column to the base or body of a concrete foundation. In this case, after fixing, the connection point of the stud is poured with concrete. The connection in which the threaded stud is used is reliable, durable and durable.

The M8 threaded stud is made of carbon steel grade 4.8 or 8.8, has a hot-dip galvanized coating and a standard metric thread pitch is 1.25 mm. The weight of one meter rod is 310 grams, one two-meter rod is 620 grams. The packing of the stud M8x1000 consists of 50 pieces, and M8x2000 consists of 25 pieces. Both packages of two versions of the threaded rod M8 weigh 15.5 kg. This hairpin is widely used in the fields of engineering and construction in conjunction with nuts and washers M8.
