a GOOD torque wrench...

Stroker, are your Snappy torque wrenches like this one?
Those can be calibrated easily once the original seal is removed and many dealers have a calibration tool on their truck. Mac torque wrenches have a lead plug in the handle that has to be removed and can't be calibrated on the truck. I have all my wrenches calibrated by a Quad State Gauging (local). tmm

Yes. My 3/8 is like that. My 1/2 is an old Torq O Meter.
