Lamp Socket Thread Sizes

Joseph T. -

Lamp Socket Mounting Thread Sizes:

  Lamp Sockets can come with Four Choices of Female Threaded Bases or Hickeys.

They will accept these male threads.

  • 1/8-27 IPS = 3/8" O.D.
  • 1/4-18 IPS = 1/2" O.D.
  • 3/8-18 IPS = 5/8" O.D.
  • 1/2-18 IPS = 3/4" O.D.

If a Socket is Not Available in a Particular Size we can use a Nozzle as an Adapter. Nozzles are Female to Male Adapters.

For Example: 

If we have a lamp pipe that is Male 1/4-18 IPS and we have a socket with a Female 1/8-27 IPS we can use the NO325 Nozzle as an Adapter.

Another way to Adapt Different Size Male Thread to Female Thread is by Using a  Reducing Coupling and a Nipple.
For Example: If we had a Male 1/2 NPT Pipe and we have a socket with a Female 1/4-18 IPS we can use the NE457 along with a 1/4-18 IPS Nipple.
