## Discrepancy

UPON UNSUCCESSFUL INSTALLATION ATTEMPT OF A NEW BOLT, THE BOLT WAS SUBSEQUENTLY MEASURED AND DETERMINED THAT THE OUTSIDE DIAMETER WAS OVERSIZED BY .001 INCH.  THE REMAINING SPARE BOLTS FROM THE SAME BATCH WERE THEN MEASURED, AND ONE ADDITIONAL BOLT WAS FOUND TO EXCEED THE CORRECT DIAMETER BY .001 INCH.
