A bolt - is a fastener product in the form of a rod with a head. A thread is cut on the bolt rod, the head usually has a hexagonal shape. With the help of bolts and nuts, detachable joints of individual parts of machines, mechanisms and structures are fastened.
Depending on the purpose, there are several types of bolts:
Foundation bolts are used to fix the equipment on the foundation.
Anchor bolts are indispensable for repair and construction works (installation of window frames and door blocks).
If there is a possibility of high temperature impact on the bolted metal structure, then it is necessary to use special heat-resistant bolts that are resistant to destruction at high temperatures. High-strength bolts GOST R 52644 are used in metal structures with increased loads, bridges, etc.
The manufacture of bolts is made of high-quality alloy and non-alloy steel, of different strength classes, coatings. Modern bolt production technology is based on the use of hot or cold tapping and thread rolling methods on special machines with subsequent heat treatment and coating.
The production of bolts can be carried out according to the customer's drawings. With a large order for standard bolts GOST R ISO 8676, GOST R ISO 4014, there may be significant discounts. The manufacture of bolts is accompanied by the necessary measurements, the products are of high quality confirmed by the relevant certificates and meet the requirements of GOST.
