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.

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.
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.
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.
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.
