In reply to k_os:
I have both types of WC half nut and rockcentrics, and some new dmms.
All the half nuts are really good. For some reason I have hardly placed an RP in the last eight years, always managing a half nut instead.
I panic bought a second set when the original WC ones had a production hic up.
The taper on the dmm ones goes the same way to the curve. The WC ones are opposite if that makes sense.
If it works like the rockcentrics , I usually find the original rockcentrics which had the tapers the same work better overall rather than the newer rockcentrics which are the same orientation as their half nuts.
Easier to understand with all types in your hand.
There is also a taper or angle on the end of the dmms , which should help overall, I expect.
I intend to file the lower edges (carefully ) so the nuts sit better in some constrictions. Quicker than waiting for the new nuts to round off naturally.
98% rating to WC.
99.5 % for dmm.
Fwiw, I prefer rockcentrics ( on dynema cord) to torque nuts, sorry Streaky.
