What is this style snap on handle called?

[Kscardsfan]

Got this partial set of flare nut wrenches off FBMP and I’m trying to get last pieces to complete the set. Is this considered the I beam handles? And if so what do I need to complete the set?

Those look to be pretty pristine vintage Snap-on RXH double-end flare nut wrenches.

I believe this was the full set was RXM605, picture below from a 'Sold Apr 9, 2025 Snap-on 9mm-21mm RXM605 Metric Double End Flare Nut Line Wrench Set' listing on ebay, if you were so inclined to hunt down a 15/17mm and a 19/21mm.

Thank you so much sir.
