I guess this is your first encounter with nuts and bolts, from here it just gets worse.
Okay, I'll bite.
Far from that.
I've probably been dealing with all things mechanical for longer than some people on this forum are alive, and invested more in tools than some cars are worth, even with a full tank of gas.
It's just all of them happened to have been metric.
If your not wanting to learn and buy tools then just take it somewhere and pay the big bucks for someone to do it for you.
There was a period in my life when I had more money than time, and this is what I had to do - just didn't have an option to do it myself then. And that was the final straw for me - "reputable shops" screwed up so much inside my mechanisms (not just cars), I still cringe looking at scars that they left.
The very last straw was when my V8 radiator blew up (straightforward replacement, righ?), but the shop managed to kill the viscous fan clutch (failed the next day), blamed it on being old, then put a dent in the door when they were fixing that (and I only saw it when I took the car home - 2 hours roundtrip), then broke the center console when they were fixing the door (and also in a way that was undetectable while I was in a shop - who would expect that they break something INSIDE while fixing an OUTSIDE problem?) - just the followups added to about a day's pay out of my pocket.
...and when two months later my window regulator (previously replaced under warranty) failed, and I started the replacement by taking off the door panel and saw 6 out of 11 clips broken, I vividly remembered the conversation I had with shop people: "But guys, the door started rattling after you replaced the window regulator?" - "Oh, they all do that with age". Age my ass, it *will* rattle if you break that many. Five cent clips, too.
So no, no matter how much you pay, your chances of getting a shitty job don't become less.
DIY since, unless it is heavy lifting.
I thought this was a pretty petty post on a Jeep, I assume you don't do any mechanical work and looking for that one tool that does all.
Not petty, bitter. I just can't wrap my mind around things like supplying metric bolts with imperial heads, or having a metric fastener on one side and imperial on the other. Arrogance? Impunity? (this comes out of discretionary income anyway, and costs a pretty penny, too). Your call to name it.
