Nuts
Nuts are fastening elements used to create reliable and detachable connections with bolts or stud bolts. The primary function of a nut is to provide axial clamping of the connected parts through tight tightening along the internal thread. Nuts are widely used in structures where secure fixation of components is required, along with the possibility of subsequent disassembly for maintenance. They are designed to perform effectively under various operating conditions, including vibration and temperature fluctuations.
