  • 10-piece pack supplies enough spacers for multi-board builds
  • M3 female threads on both ends secure PCBs without extra nuts
  • 20 mm body length sets a consistent gap for 180 210 250 class racks
  • 5 mm outside diameter fits tight chassis cut-outs
  • Black anodised aluminium resists corrosion while staying lightweight

M3 aluminium standoff spacers for 180 210 250

These M3 x 20 mm aluminium standoffs suit builders assembling 180 210 250 class rack equipment. The female-threaded columns provide secure spacing between boards or panels. A pack of 10 pieces covers typical multi-layer builds.

Thermal and mechanical behaviour

Aluminium construction conducts heat away from mounted components while adding minimal mass. The 5 mm outside diameter and 20 mm body length keep the stack compact. No moving parts mean silent operation and no power draw.

Ten-piece pack simplifies inventory

Ten identical spacers arrive in one bag so you can complete a build without sourcing singles. The black anodised finish resists corrosion and matches dark chassis aesthetics. No extra tools or software are required.

Questions about this item

How do I install the M3 x 20mm aluminum standoffs into a 180 210 250 class rack, and what step is often missed?

Screw the M3 female threads into the rack's pre-tapped holes by hand, then tighten gently with a hex key; the step often missed is checking that both ends engage fully before applying final torque.

What maintenance or replacement will the 10-piece black aluminum standoff set need over time?

Inspect the anodised finish and M3 threads periodically for corrosion or galling; replace any spacer that shows stripped threads or deformation to maintain alignment in the rack.

What limit appears first when the M3 x 20mm standoffs are under sustained load in a rack build?

The 5 mm outside diameter and aluminum material mean the compressive yield of the spacer body is reached before the M3 thread shear strength, so watch for body deformation under heavy static loads.
