Bolt length may vary after the bolt heads are sheared off. Bolt heads are not required to be removed as long as the appropriate bolt torque is achieved.
When using an impact wrench, size the wrench for 2x the bolt torque. If using an air impact wrench, check the air pressure, torque rating and air flow requirements before starting installations.
