What testing should be performed on high-strength bolts upon delivery from the manufacturer?
To ensure that the delivered fasteners comply with the purchase requirements and furnished documents, upon receipt, the purchaser should verify that: • The bolts and nuts are marked as specified. • The manufacturer’s mill test report shows a chemistry that meets the requirements for the type of bolts and nuts specified. • Certification numbers appear on the product containers and correspond to the certification numbers on the mill test reports for the fasteners. • Mill test reports are supplied to both the purchaser and the testing laboratory responsible for quality control. • If the fasteners are galvanized, rotational capacity test results and nut lubrication should be verified to be in compliance with the appropriate ASTM specification requirements. A bolt tension calibration device (see 6.9.1 and 6.9.2) should be available in the shop and at the jobsite at the beginning of bolting start-up.
