SPA 10 Round Plain Hole Spacers
PSM SPA-10 Round Plain Hole Spacers are plain-hole round spacers designed to let screws or shafts pass through without threading. They support components while providing clearance and alignment.
Advantages
> Spacers with through holes
> Light weight
> Good thermal stability for Acetal
Materials Available
AC – Acetal
B – Brass (electro nickel plated)
SS – Stainless steel 18/8
MS – Mild Steel (zinc plated)
Dimensions
Common Uses
- As standoffs or bushing guides
- In assemblies where a shaft or connector must run through spacer
- For spacing between panels or plates without threading
Selection Guidelines
- Choose material based on load, environmental, and electrical requirements
- Match external diameter so it fits your assembly conditions
- Pick length that gives proper clearance without overextending

Frequently Asked Questions About Round Plain Hole Spacers
What are PSM SPA 10 Round Plain Hole Spacers?
PSM SPA 10 Round Plain Hole Spacers are unthreaded cylindrical spacers that allow screws, bolts, or shafts to pass freely through a clearance hole rather than threading into the spacer itself. Their function is pure separation and alignment — providing a consistent, reliable standoff distance between panels, plates, or components without any internal thread engagement.
What is the key difference between SPA 10 Round Plain Hole Spacers and the SPA 04/05/06 Threaded Acetal Spacers?
SPA 04/05/06 have internal threads moulded into the acetal body, so fasteners screw directly into the spacer to create a captive connection at each end. SPA 10 have a plain through-hole with no thread — the fastener passes all the way through the spacer and is secured by a nut, washer, or shoulder at the other end. SPA 10 Round Plain Hole Spacers are the right choice when you need pure spacing or bushing-guide function without any threaded interface within the spacer body itself.
When should I choose an acetal SPA 10 over a brass or stainless steel version?
Four material options are available: Acetal (AC), Brass with electro nickel plating (B), Stainless Steel 18/8 (SS), and Mild Steel with zinc plating (MS) — matching the same material range as the rest of the SPA series so engineers can maintain material consistency across a mixed assembly.
What are the main uses of Round Plain Hole Spacers in assemblies?
Three primary uses are listed: as standoffs or bushing guides to maintain separation between components, in assemblies where a shaft or connector must run through the spacer freely, and for spacing between panels or plates where no threaded engagement within the spacer is required. In all three contexts, the spacer acts as a precision distance piece that locates and supports components rather than fastening them.
How do I select the correct SPA 10 Round Plain Hole Spacers for my application?
Three selection guidelines apply: choose material based on the load, environmental, and electrical requirements of your assembly; match the external diameter so the spacer fits correctly within your assembly envelope; and pick the spacer length that gives the proper clearance between components without overextending the stack height.
