Is that for Snap On tools? My Snap On guy has been calibrating mine WITH certification if I want it for as long as I can remember for free.
Correct. Every good engineer will allow for what's known as a "safety factor". They know that no theoretical torque value, or torque wrench, will ever be 100% accurate. For example, I work on some military jet parts, and right now I'm looking at an assembly drawing that says "62-72 in/lb" for a small nut & bolt fastener. That's 67 plus or minus about 7.5%.You just have to wonder. If the specs call for 65 foot pounds is 60 or 70 unacceptable? Everything else in the engineering world has tolerances that they need to stay inside of. Usually +/- 5% give or take. Should torque wrenches be any different?
Do you have some sort of account? I rolled up on 3 different trucks and they all gave me a different price but it was around 30-50 with a cert being $70. Ill send you mine!
