Torque Testing

[Dobe]

We are torquing down bolt at between 48 to 54 ft. lbs. If we are consistly getting 50 - 52 what should the breaking point be when we test them? We are also auditing torque angle. I believe that is set between 10-30 degreees.

What kind of bolt, in what kind of application?

Typically, structural engineers shy away from torque calibration of bolts because in our world it tends to not be very consistent.
