What’s wrong with purpose made pushrod, with thread on one end, Z bend on the other? Fairly inexpensive from all the usual UK suppliers, M2, 2.5 and 3 freely available, as are locknuts for additional security. If one end of the rod is fixed, e.g. Z bend, it can’t rotate anyway.
Agree with Gangster re variable thread sizes. My preference is for relatively long clevises, Kavan e.g., aiming to have the entire clevises thread filled by the rod thread and if they get too short I make up another one. Then it’s threadlocked and has fuel tube over the clevises arms pushed close to the control horn to prevent springing off.
The only failure I’ve had was clevises from an ARTF Yak where the pins were weak, luckily failing prior to maddening, so I threw them all out. But 2mm plain rods are no problem. Maybe i'm not looking in the right places.

The main problem was finding a UK shop that sold 800mm & longer 2mm rods with a thread. But plain 2mm rods are no problem. Might be unlucky in where i am looking.

I've used these guys before to get 1 metre lengths **LINK** so I can make custom lengths and cut a thread at both ends.
