M2.5 x 55mm Female/Female Hex Standoff | 5mm A/F | 9mm Female Thread Length | Aluminium

This M2.5 x 55mm electronics standoff provides a precise spacing point between compatible components while accepting threaded fasteners from both ends. The 5.0mm across-flats body can be held with a suitable spanner during installation which helps maintain alignment in equipment frames, mounting plates and serviceable panels. This version is not listed as through-threaded. A defined female thread length is specified for the product, so the description does not treat the bore as a continuous through thread. The Aluminium construction keeps the standoff lightweight while providing a durable spacer for suitable electronic and mechanical assemblies.

What Are Female/Female Hex Standoffs?

Threaded Hex Standoffs provide mechanical separation between boards, panels and other components. Their hexagonal body allows the spacer to be held with a suitable tool while the female threaded ends provide reusable fastening points during assembly and servicing.

Common Applications

  • Telecommunications: Provides spacing and fastening within communication hardware and rack-mounted electronic assemblies.
  • Computer Hardware: Supports PCB and module spacing inside compatible computer, embedded and control equipment.
  • Laboratory Equipment: Creates secure separation points within instruments, test rigs and technical devices.
  • General Engineering: Provides a threaded spacer where two components need a defined gap and fastening from both ends.
