High-Strength Bolt

High-strength bolts are used in machine building, construction, and the erection of metal structures. High-strength bolts have a tensile strength of at least 800 MPa. They are made of steel and comply with property classes 8.8, 10.9, 12.9. The fasteners are manufactured by hot or cold rolling and are necessarily heat-treated. Bolts may have various coatings: electroplated zinc, hot-dip zinc, etc.

Such bolts have high strength, withstand heavy loads, are resistant to vibration and have anti-corrosion properties. They have low adhesion and can work in a lubricated environment under friction and sliding. They are resistant to aggressive environments, seawater, acids, and solutions. One of the most common types is the bolt to GOST R 52644.
