What is the difference between a spacer and a standoff?

A plain spacer is an unthreaded tube used to create a fixed gap between two parts, with a fastener passing through it. A standoff typically has internal or external threads for direct mounting. Listings in this category are primarily plain spacers; check the product specs for bore type before ordering.

How do I choose the right spacer size?

Match the inner diameter to your screw or bolt size (for example an M3 spacer for an M3 screw), then pick the length equal to the gap you need to maintain. Confirm the outer diameter fits your mounting footprint and select the material based on strength and environment.
