59mm Thumb Screws for DB9 Serial Port Connector (Set of 2)

This kit includes two thumb screws designed to replace the female nuts on DB9 serial port connectors. They provide a tool-free way to secure a connector to a terminal board or mating port, letting you tighten or loosen the connection by hand instead of using a screwdriver or wrench.

These screws are sized to fit standard DB9 connector hardware, such as parts commonly labeled FE-DB9-M and FE-DB9-F. Only the thumb screws are included in this kit – no nuts, standoffs, or connectors are provided.

• Total length, end to end: 59mm
• Exposed metal shaft length: 50mm
