A03Fasteners & standoffs

Join the plates and support the electronics stack.

Manufacturers & products

Screws, standoffs, nuts and spacers set mechanical alignment and electronics clearance. Hardware strength, dimensions and electrical isolation matter independently of the frame brand.

American sourcing options appear first. A U.S. company or distributor label does not establish U.S. manufacturing. The origin notes identify the specific evidence and any limits.

What remains unverified

  • The public kit pages do not establish lot-level screw certification or manufacturing country.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

  • Thread and pitch

    Confirm nominal thread, pitch and mating insert compatibility.

  • Length and engagement

    Different plate stacks require different fastener lengths.

  • Head geometry

    Countersunk, button and socket heads fit different recesses and bearing surfaces.

  • Material and strength

    Steel, aluminum and nylon trade mass, strength and electrical conductivity.

  • Stack spacing

    Standoff length sets the available clearance and board-to-board separation.

  • Isolation

    A rigid spacer is not an elastomeric vibration isolator.

  • Retention design

    Choose hardware that matches the frame’s documented retention and clamping concept.

  • Kit specificity

    Confirm that a replacement set belongs to the correct frame revision.

Selection & integration notes
  • The rigid Pololu spacer is a generic electronics spacing option, not a structural arm fastener.
