I'm researching the best types of ratcheting wrenches to get. I'm more interested in increasing capability than increasing speed. If I can access a fastener with a new tool that otherwise would have required me to take half of the engine bay apart, that is a great tool. I'm not interested in saving 10 seconds on removing an easy fastener.
It got me thinking, for fastener access, what is the order of tools of preference to choose? I've been reading a lot of threads and here's the summary of what I think I learned:
I think you want to break the fastener with a box end first. Which may require a standard 15 degree, a 0-degree offset, or a deep 45 degree. And you may be able to get away with a regular length, but you may need a long length either for access since your hand can't fit in the spot where a regular length wrench would be, or maybe long length for extra torque. Or you might need stubby length for access.
If you can't get a box end on to break it, you can try to break it with an open end, but the torque capability is much more limited due to less wrench surface area engagement with the fastener. Snap On makes flank drive open ends that bite into fasteners, which some argue can leave marks on the fastener (and some disagree), but may be necessary to get enough torque.
Once it's broken, you could in theory keep using that tool to continue turning the fastener until it's loose, you had the clearance to get that initial tool on to turn it slightly, which means you can keep turning it. But it will take a long time, so some ratcheting tool is introduced.
If you have clearance, go with a socket and ratchet. All sorts of lengths and depths to choose from. I think this is the original gold standard. Then we have ratcheting box end wrenches with reversible being the first choice. The problem with reversible is that it requires more clearance to fit the head in. Assuming unlimited clearance, I think mechanics might even choose a reversible wrench over a socket/ratchet because of the speed in picking up one single tool, rather than connecting a socket + ratchet.
If there's not quite clearance for a reversible wrench, then they make non-reversible. These tend to be in 0 degree offset or flex, because having a fixed 15 degree non-reversible wouldn't be symmetrical in use, since you' have 15 degrees in one direction and 165 degrees in the other direction. Flex is going to be floppier than 0 degree offset but you may need the angle. There are lockable flex, but it will limit you in specific locking positions.
Based on this, it seems like the order of access for tools from unlimited access to limited access is:
I've come to realize that I work primarily on Japanese cars and most of the fasteners under the hood are 8, 10, 12, 14 which means I can actually get away with 2 wrenches, an 8-10 and a 12-14, and buy one of every style of wrench, and not fill up an entire drawer with ****. I think the 17s and 19s are mostly in places where you can fit sockets without issue.
