the op claims to be a heavy diesel mech that needs some large wrenches. probably has 1000's if not 10's of 1000's in tools and storage.
commentors will tell him that he should use truck brand ratchets, wrenches and sockets or at the very least some of the better respected brands with good fit, finish and ergonomics, things that should be at least somewhat important in a pro-environment.
guys will drop 50 dollars or more on pliers and 100 or more dollars on ratchets with hardly any material in them, yet he is getting advice to go el cheapo and save maybe 40 or 50 bucks on a set of wrenches that will fill a 5-gallon pail.
i am hardly a tool snob and will almost never tell anyone to waste money but i find it comical that someone insinuates that buying a klutch branded tool from northern tool is wasting money and for show
Slow down, I'm not there yet...
First, while I don't track the combined monetary value of the tools & tool storage I own, if I were to either guess or literally put a price on every tool I currently own + my tool box (as of this post) and add it up, it would probably be approaching the neighborhood of a $10k grand total. For the record, most of my basic tools and metric tools are Snap On, but I don't own a Snap On tool box.
I'm not telling you this to brag or anything like that, the reality is that value/prices up add very quickly, especially when we're talking about tool trucks. I recently traded in some unused Snap On tools to my Snap On dealer, and he gave me over $1,600 in credit towards my account, and all I had was an 8" Milwaukee zipper tool bag full of tools, it was nothing special and nothing big.
Secondly, I am a heavy equipment mechanic/technician with a focus on Caterpillar equipment as my employer is a rather large CAT dealer (parts/sales/service/rental) here in the Southwest (AZ/CA)... However, I just got this job. I'm also coming into this opportunity as a former automotive mechanic. Working on heavy equipment is completely new to me. Like my tools, I'm nothing special. I'm running off a provided list of tools I'm expected to have, advice from GJ members and the few YT videos I can find. The rest will come with time and advice from coworkers. These wrenches are no exception.
Third, when it comes to SAE tools and something like these large size wrenches specifically, I have no plans or desire to spend Snap On/tool truck money on these tools. If I find that I'm using specific SAE tool all day every day or whatever I have just isn't working/holding up to the use, I'll consider upgrading to a higher quality version. But until such time, I'm sticking to the basics and whatever I can afford at the time. Although I'm trying to avoid buying made in China and buying HF tools when and if possible.
