Threaded stud is a fastener that is widely used in construction, mechanical engineering, furniture and automotive industries, in repair work and other industries. This fastener is designed for building various structures and connecting parts,
far away.
Zinc-plated threaded stud is a metal rod (rod), along the entire length of which a metric thread is applied by knurling. Due to the fact that the hairpin is often used in conditions of various temperature extremes and high humidity, it is treated with zinc or made of stainless steel. A meter rod with a thread without coating (black) is operated in more gentle conditions, where an aggressive environment cannot cause metal corrosion.
Stud sizes and designs are strictly standardized. Production material, accuracy class, basicdimensions, conditions of transportation and storage, as well as possible deviations from the normative rules are regulated by the DIN975 standard. 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. The threaded stud is used with all imported fasteners. With its help, the following tasks are solved:
- fixing suspended ceilings, frames, cable boxes and other fixtures;
- installation of heating and ventilation systems;
- construction of frame houses;
- connecting elements of wooden logs, boards and beams;
- formwork while working with concrete;
- installation of billboards;
- adhesion of materials during finishing, roofing or repair work;
- installation of floors, plasterboard partitions;
- other general construction works.
Most often, a threaded stud is mounted with hammered anchor fasteners, metric nuts and washers, connecting sleeves and a perforated profile of different lengths. Sometimes it is used as a fixing or tightening element in the installation of formwork or plays the role of a suspension. Length
threaded rod can be cut to the required size by cutting. In addition, it can be used in the construction of foundation anchor bolts as an integral element - for mounting a metal sub-column to the base or body of a concretefoundation. In this case, after fixing, the junction of the stud is poured with concrete. The connection, which uses a threaded stud, is reliable, strong and durable.
The M8 threaded stud is made of carbon steel of strength class 4.8 or 8.8, has a hot-dip galvanized coating and a standard metric thread pitch of 1.25 mm. The weight of one meter rod is 310 grams, one two-meter rod is 620 grams. The package of the M8x1000 stud consists of 50 pieces, and the M8x2000 - of 25 pieces. Both packages of two types of M8 threaded rod weigh 15.5 kg. This stud is widely used in the fields of mechanical engineering and construction together with M8 nuts and washers.
