22、urpose, and shall be identified on the drawing by their part numbers. Commercial utility parts such as screws, bolts, nuts, cotter pins, etc., may be used, provided they possess suitable properties and are replaceable by the AN or MS standard parts without alteration, and provided the corresponding
23、AN or MS part numbers are referenced in the parts list and, if practicable, on the contractors drawings. In the event there is no suitable corresponding AN or MS standard part in effect on date of invitation for bids, commercial parts may be used provided they conform to all requirements of this spe
