Overall, is it safe to assume that most tools for this are metric? And are deep well sockets needed a lot?

Just about ready to buy some new sockets, and wanted to know what to get.

Thanks

 

Metric brother. However, some of the metric sizes are very close to standard. example, 5-6mm=1/4", 8mm=5/16", 10mm is very close to 3/8", 11mm= 7/16", 13mm=1/2", 14mm=9/16", 19mm=3/4", 22mm=7/8", 25mm=1", 28mm=1 1/8" and so on. Most are very close and usually work. Not sure about the deep wells though.

 

Thanks....I think I need metric deep wells.
