> Adjustable wrenches exist for situations where you don't have the proper size on hand.

I would say convenience and use case are just as important. A crescent wrench is non marring unlike alligator jaws or vise grips. It's also perfectly fine for low torque applications. It isn't for torquing lug nuts.

I have a wonderful wrench and socket set in standard and metric measures. It's in a nice case on a shelf in my garage. My crescent wrenches are hanging 5 feet away on a pegboard.

I needed to loosen an RP-SMA connector the other day. What size is that nut? Do I want to break out my wrenches and fiddle? Nope, the nut is only just beyond finger tight so two crescent wrenches and 5 seconds to get it off.

Any 5/16" wrench for loosening. For tightening, ideally the appropriate torque wrench for the particular connector (material & grade) should be used.

Or other stores. RF connectors should be torqued to a specified torque listed on their data sheet. Improper torque can cause damage. Usually for equipment using SMA connectors this isn't a big deal (just replace the connector, they're cheap and the torque wrenches are expensive), but for the really high frequency stuff like 1.85mm connectors the connector itself is $70-300 so spending $100-400 on a torque wrench is reasonable.

This was a $5 WiFi antenna I bought off Amazon for an ESP32-WROOM-32UE bolted through an enclosure, I'll stick with my crescent wrenches.
