Pull screws– also known as trapezoidal bolts – are a patent that allows transmission of propulsion, and more specifically, the conversion of rotational motion into progressive. This type of mechanism consists of three parts: a groove shaft and a nut. These solutions are used in the construction of machine tools of various types to mention lathes, milling machines and laser cutters. However, this is only part of the many applications that screws find themselves in.
Pull screws are also suitable for the construction of machines for the printing, textile and mining industries. Some types of pull screws are also used when closing transformer station fire-proof chambers. An important advantage of the offered solutions is their durability. It is worth adding that thanks to their parameters, the pull screws are ideal for working even with the highest loads.
