no, just shove the wires into the collar, tighten the set screw down. By twisting the marr clockwise it will twist the wires properly, and lock together. The marr usually has a copper cone inside that helps twist the wires properly. You must still twist the marr cap. and yes, they are spendy.

Hmm... I would still have to twist the wires before inserting into the collar, no?  At least, overlap under the "set screw", so that the wires don't pull out.  Thanks, I'll look into them.  Man, they are pricey!

Linesman pliers for twisting. However some marettes come in two parts: the cap and a collar with a set screw. The collar part you tighten down the set screw with a screwdriver, then twist the marette cap onto the set screw collar

What tool or adapter do you use to twist electrical wires?  I don't
trust those "Wago" connectors, because they only have 2 points of
contact.  I prefer to twist the wires for contact surface, and use wire
cap connector to hold the twisted end together.

1.  I used to use linesman's pliers, as usual.  But, my wrists are not
what they used to be, and carpal tunnel and tennis elbow don't help
either.  So, I'm looking for an easier way, more power tool way.

2.  Amazon has lots under "wire twisting tool" search.  But, they don't
grab the wires and apply tension, so the twisted wires don't end up
straight.  Also, most adapters wrap wires around 1 centre wire, but
that's not ideal for "wire cap connectors".

3.  I made 2 adapters (pictures attached).  But, they don't apply
tension, so the twisted wired are not straight.  In fact, the results
are ugly.

4.  Right now, I am using drill chuck to hold the wires in tension. But,
I'm looking for something lighter.------------------------------------
