My old boss told me to never trust a new torque wrench right out of the box
When I started at a regional shop in Phoenix, my lead gave me this advice on day one. I was working on a Cessna 172's nose gear assembly about six months ago and grabbed a brand new, still sealed torque wrench from the supply room. I figured it was fine, it was new. I torqued the bolts to spec, 250 inch-pounds, and signed it off. Two weeks later, the plane came back with a shimmy complaint. We found the main bolt had worked loose. The new wrench was off by almost 30 inch-pounds. My lead just shook his head and said, 'Told you. Calibrate first, always.' I had to eat the rework time. Now I check every single tool, new or old. Do you guys have a standard calibration check you run on new tools before putting them to work?

Trusting new stuff without checking is how you get burned in life, not just with tools lol.

That's just wasting good money and time. A sealed tool from a known brand should be trusted, or what are you even paying for. Your loose bolt was more likely bad technique or a worn part.

My buddy's new impact wrench had a cracked housing right out of the box last month. Manufacturing defects happen to every brand, no matter the price. A quick function check costs you two minutes but can save a whole weekend project.
