Hexagonal spacers and standoffs are a cost-effective and efficient way to provide support, positioning and spacing to PC circuit board assemblies, panels and doors.  The use of spacers in motherboard mounts allows the components of each assembly to be adequately positioned and to create space between them, avoiding a short circuit and making devices safer.

Many computer assemblies use a metal hexagonal threaded spacer as they can be used in high temperature environments, which is important as the circuit board may get hot during operation.  Another advantage is that they will also allow a circuit to be maintained.  Common materials for hex spacers include mild steel, stainless steel and nickel-plated brass.

Technifast offer hexagonal threaded standoffs in a variety of sizes from M2 through to M6, with outside diameters from 4mm to 10mm, the majority of which are stocked in our Corby-based warehousing facility.  We also understand that a customised spacer may be needed and offer a bespoke standoff and spacer manufacturing service to cater for individual requirements.


  • MA - Mild steel, grade S300Pb, zinc and clear chromate finish
  • ML - Brass, nickel plated
  • MI - Stainless steel (stocked in M3 & M4). Larger sizes can be manufactured to order.
