Technifast’s PCB spacer and standoff range forms integral components in a wide variety of electronic hardware assembly applications, such as raising a Printed Circuit Board (PCB) above a surface to stop the two parts touching each other.

The majority of our standard range is stocked in our warehouse facility, ensuring we can meet the demands of customers quickly and cost-effectively. Standard nominal thread sizes range from M4 through to M12 in the round threaded spacer, with diameters from 7mm to 15mm.  The size range of standard hexagonal threaded spacers spans M2 to M6 with outside diameters from 4mm to 10mm.  Threaded spacers and standoffs are available in three configurations: male-female, male-male and female-female.

We can also offer the manufacturing capabilities to produce bespoke threaded spacers to a customers’ specification, in a variety of materials.  Technifast are specialists in stainless steel and offer PCB spacers and standoffs in 303 and 316 stainless steel grades as well as mild steel which offer good heat resistance for environements within electronic hardware and helps to conduct electricity when there is a need to maintain a circuit.



  • 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.
