Depending on the actual friction coefficient present, that torque will result in about 3,000 pounds of clamping force on that size/pitch bolt, which is about 25% of their tensile strength. Lots of margin in bolts holding aircraft together is a good thing! Don't squander the margin by honking down bolts by "feel".
A separate but related fun-fact: Critical bolts subjected to cyclic loads (think about the studs holding the cylinders on) are often specified to be torqued to a value which maximizes their fatigue life. Torqued below or above the spec and their fatigue life will likely be lower.
