SMA connector thumb screw

SMA connector thumb screw

Inspired by the great "SMA cable thumb screwdriver / key 8mm" by Tomaskom_cz (, I scratch (re-)designed this from the ground up to fit my needs (and just give it a other try on 3D design).

The difference are :

  • a beveled edge on the bottom so the positioning of the thumb screw on the connector goes more smoothly.
  • base shape isn't a cylinder but a 12 sided polygon giving me a little more control on the front end.


I'm even thinking about to make few a smaller versions of this one to glue them on to my fieldradio SMA cables. Because connecting cables in the field can be a tricky thing :-)
