Like TechnoDuck said, The quality at FLAPS is poor. I bought a set from AutoZone and this was the result after one use. The 8mm for the CV bolts-I did clean out the recess-chipped but I was able to finish. The 12mm for the FW bolts chipped as well but I filed the head down to get the last bolt in at 65 foot pounds.
Have a tube of CV grease to repack the joints.
