Be sensitive to crosstalk issues as bolts may loosen as adjacent bolts are tightened—re-tightening with a calibrated torque wrench may be necessary. The snug-tight connection for multiple bolt rows behaved stiffer and stronger than its fully pretensioned counterpart. Bolts can be pretensioned and still be considered bearing connections, such as in the use of tension control bolts. The tensioned bolt indents the sur­ face of the connected steel adjacent to the slot edge and provides "keying" action. the connection. freelance remote jobs without a degree .
