Fun fact
It is unusually cheap because it has almost no parts, the solid copper core of the coax cable IS the connector’s centre pin.
Tips & tricks
Hand-tighten only, over-tightening bends the centre wire and kills the signal.
Philosophy
Frugal genius. Why machine a centre pin when the cable already has one? The F-connector simply uses what is there.
