小型和大型圓形發射器螺絲（6入）

The little bag of six covers both my small and large round transmitters without any loose fit issues. Threads catch cleanly on the first try, so no cross-threading frustration when I’m swapping between rigs in a hurry.

Finally, a screw set that fits both my tiny RX-090 and the bigger round transmitters without any wobble. The six pieces cover everything I’ve got, and the threading bit into the receiver holes just right.

The threading on these screws is clean and precise, so they seated perfectly into my round transmitter without any stripping. The set of six covered both my small and large units, which was a nice bonus for the price.
