I'm a belt and suspenders kind of guy, but even I get tired of all the 'can't trust the torque stick' constant posts.
No, they ain't perfect.
Neither is your torque wrench.
Or the clown using it...
Pete's sake, my wife had a set of tires put on a van once. They used a torque wrench. Then a wheel started coming off on the way home. Yep, torqued perfectly, except for the one wheel they forgot to even tighten the lug nuts.
15 down perfectly, 5 overlooked.
Test a torque stick when you first get it. Use a tiny little bit of common sense and the same settings on the same gun next time and you will be closer than the illegal alien teenager who probably put your tires on at the tire store.
