Kierteitetystä

Kierteitetystä is a Finnish word that translates to "threaded" in English. It refers to something that has been made with a screw thread. This can apply to a variety of objects, most commonly fasteners like screws and bolts, as well as the holes they are designed to fit into, known as nuts or tapped holes. The characteristic spiral groove around a cylinder is the defining feature of a kierteitetystä object.

The purpose of a thread is to create a strong mechanical connection that can be easily assembled and disassembled. When a screw or bolt is turned, its threads engage with the corresponding threads of the mating part, drawing them together and creating a secure fastening. The pitch of the thread, which is the distance between adjacent crests, determines how quickly the parts come together with each rotation. Different thread forms exist, such as metric, unified national, and acme threads, each with specific applications and standards.

Beyond fasteners, the term "kierteitetystä" can also describe other items with helical grooves. For instance, a pipe might have kierteitetystä ends for connecting to other pipes or fittings. Similarly, certain shafts or rods might be kierteitetystä to engage with gears or other components. The manufacturing process for creating kierteitetystä surfaces typically involves either cutting or rolling the threads onto the material.
