Spacers are generally used as spacing connections. Due to their diversity, the wide range of design concepts can be realized with spacer bolts and practically every application can be realized using the appropriate spacer bolt.
The design and assembly of thin plates makes it extremely difficult to work with counterbores or internal threads. Therefore, spacer bolts are often used on plates, sheet metal or printed circuit boards (PCB).
The selectable assembly threads, the individually configurable length of the spacers, and the selectable length tolerance via the [LKC] option offer great design freedom compared to conventional mass-produced products. This advantage is particularly important if, for example, plates of different thicknesses or particularly thin plates are utilized.
For applications with particularly high positioning requirements, it is recommended to combine shim rings with a spacer. These can be configured in thicknesses from 0.01 to 1 mm and integrated as an additional compensating element.
The assembly of hexagonal spacers is particularly easy with the hex, since they can be held against one another with an open-ended spanner. With round spacer bolts, this can be realized with a spanner flat. The spacer bolts are also available with one-sided or two-sided internal thread (long nut). For precise positioning of a spacer bolt with an internal thread or external thread, MISUMI also offers a centering pin in the ISO tolerance h7.
This variety enables virtually barrier-free assembly of the components to be joined with screws, internal threads and external threads or nuts.
