Bolts and Nuts

Bolts and nuts are standard, widely used mechanical fasteners for connecting components in structures, machinery, industrial equipment, and construction projects. They can be made from carbon steel, stainless steel, or high-strength alloys with surface hardness of 200–400 HB and tensile strength of 600–1100 MPa. Bolt diameters range from M3 to M36, with lengths from 10 to 300 mm. Threads are precision-made according to ISO, DIN, or ANSI standards, providing high tensile and torque load capacity. Galvanized, chrome, or epoxy coatings increase corrosion and wear resistance.

Nuts are paired with flat, spring, or anti-slip washers to ensure secure, uniform connections. Suitable for light and heavy machinery, production lines, steel structures, and industrial projects. Mechanical design and manufacturing standards reduce loosening, increase connection durability, and extend structural service life. High strength and dimensional precision ensure safe and stable performance.
