The nut below the handle was the best thing since sliced bread! I have ratchet wrenches that are perfect for them. Other brands, Craftsman comes to mind, with the square shaft are more cumbersome to use since you usually need a Crescent wrench. On those smooth handles of the Snap-ons, and others, I often wrapped some rubber high-voltage electrical tape around them for a better grip, especially when my hands got slimy with refrigeration oil or other greasy (stuff). I don't think I own a complete set of any one brand of screw tools. My all-time favorite is the 6-in-one driver: two sizes each of flat and Phillips, and 1/4 & 5/16 nut drivers. My tool pouch or tray was best to consolidate as much as possible when working on roof-top RHVAC units or in crawl spaces, top of walk-in coolers/freezers, etc. I believe in all the schools in Pittsburgh Public Schools there are several complete sets of tools in the ceilings, behind air handlers, etc.! Also, those black handles I liked to wrap a piece of white electrical tape...God I'm getting work flash-backs! I've only been retired 9 months!
