Hit 500 engine hours on one torque wrench, and it still reads true
I bought this Snap-on click style torque wrench back in 2017 for my side work, mostly doing prop flange bolts and cylinder base nuts. Guys at the shop told me I was wasting money on calibration checks every year, said just trust the click. Well, last month I sent it in for its annual check, and the lab said it was still within 1 percent across the whole range. That surprised me because I've dropped it twice, once off a stand in Bakersfield, and I always thought those drops would throw it off. But here's the thing, I log every use in a little notebook, and 500 hours of actual torque applications is way more than most guys put on a wrench in a decade. I know the popular opinion is that you need to replace or recalibrate often, but my experience says a quality tool with regular care will outlast the doubters. Has anyone else pushed a tool way past the recommended service interval and had it come back clean, or am I just lucky?

Getting a wrench to survive 500 hours of actual use is not the same as it still being accurate. A click wrench can feel and sound fine while the spring inside has lost tension, so unless you are testing it against a known standard you have no real way to know it is holding. Sending it in once a year is not being paranoid, it is just how you actually confirm the thing still works. Your lab result came back clean this time, but that is one data point, not proof the whole rule is wrong.
