Yes, standard 1/2x13. The heads are a little different. If you are going to use a winch, use different head bolts. Most thieves just check to make sure you don't have lock down. Then grab their standard ratchet wrench and socket. They probably don't have the mind to pull multiple size sockets. Don't forget to use antiseize on them also. Helps with the removal when necessary.
Mine are SAE and Metric.
