Description/Basics

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.

Frequently Asked Questions (FAQ)

Question:

Do you also have hollow spacers?

Answer:

Spacers or spacer bolts are generally made of solid material. However, if a hollow spacer is required, MISUMI also offers spacer sleeves. These are configurable like the spacers and can be adapted to the required dimensions. For precise distance, we recommend selecting simultaneous grinding spacer sleeves.

Question:

Are the spacers stainless?

Answer:

The spacers and spacer bolts can be selected in stainless steel and in steel with surface coating. To select the coating, the spacers are available in burnished, chemically nickel-plated, clear anodized, chromated. Thus, depending on the application, the spacer bolts are protected against corrosion.

Question:

Do you have spacer bolts with an undercut?

Answer:

MISUMI offers an additional option [FC] the spacer bolts for an undercut. With this option, a cutout is added to the external thread of the spacer bolt. The dimensions of the cutout can be found in the overview as a PDF.
