Bolts; ISO standard:ISO 4762
(3 570)Bolts are mechanical components for connecting two separate materials. It is used in the vast majority of devices and machines, and its operation relies on the friction of the working surface of a thread. It is classified as a direct, separable connection, which makes it a universal solution in design. The basic criterion for selection is thread diameter – the external thread of a bolt should match the internal thread of the hole. While the most common threads in Poland are metric threads (M), some of the connections use the imperial units – inches. Another key feature is the head and its cutting. There are cheese, hexagonal, cone, or spherical heads with imbus, square, Philips, Pozidriv, or Torx cuttings. Each of them has different mechanical parameters. To fasten a given type, you need to use a dedicated bit. You should also consider the strength class. It usually comprises two numbers. The former references the minimum tensile strength (divided by 100), and the latter denotes the ratio of the yield strength to tensile strength (multiplied by 10).
Bolts available at TME
TME online store distributes bolts and screws with a wide selection of threads and lengths. Our offer includes both metric (M1 to M16) and imperial bolts. Available lengths range from 2 to 260mm (depending on the diameter of the thread). Furthermore, the catalogue comprises threaded rods, lifting eye bolts, and setting bolts. Search filters enable you to refine your search to a particular type of hear or cut. The wholesaler offers bolts made of stainless steel, galvanised steel, polyamide, or brass. Each product comes with a parameter description and a list of standards met (DIN, ISO). TME's offer includes i.a. products from renowned manufacturers Bossard and Kraftberg.
