Some calibration standards do not have a rotating locking collar. In that case there is no way to avoid rotating the center pin unless you use those very short male-female SMA adapters sometimes called "connector savers".?? The best way is to buy a set of calibration standards that actually have rotating locking collars.

Try as I might, I cannot keep the pin+back assembly still while screwing the short and/or load calibration piece down in the SMA socket!
Should I add some grip to their backs, with glue or solder? Should I file out a slit for a screwdriver?
Or just give up?
