What it is

A zinc-plated M3.5 machine screw, 75mm long, with a raised countersunk head, made by Unicrimp. It is used to fix wiring accessories such as light switches and socket outlets to their back boxes.

Signs this part needs replacing

  • The screw head slot is stripped or rounded
  • The screw has rusted or corroded
  • The thread is worn and no longer holds
  • The accessory will not sit flush because the screw is the wrong length

Before you order

  • Confirm the accessory takes an M3.5 thread
  • Confirm 75mm suits the depth of the back box or mounting
  • Count how many screws the job needs before ordering a full pack
