Review on DURATECH Flare Nut Wrench Set, SAE, 3-piece, 3/8'', 7/16'', 1/2'', 9/16'', 5/8'', 11/16'', High-Quality CR-V Steel, Organizer Pouch Included by John Maskirta

I've used these in my profession for over 2 years and they hold up well. No rust to this day and I live on the coast. My only complaint is that the surface is too thick for the small/close fittings. They're heavy which some may like, but I carry a tool bag and would prefer a thinner design. That aside, this is a great value for the money set and will last many years by my estimate. If its just a few different sizes that you use, then I would go higher end and get the ones you need.
