These are not magnetic.

Which sizes of all thread fit this shaft?

Each of the nut drivers included in this set have a different sized diameter full hollow-through shaft to accommodate the rod size that corresponds with the nut driver size.

Do these come in a plastic tray to help creek them organized in a tool box?

Best nut drivers ever!
Just bought this set and I have had Klein nut drivers before but this heavy duty set is very nice. Because the hollow shaft extends through the handle and the shaft allows you to put a wrench on it to help turn, I have been able to reduce the number of tools I carry. That's a big deal to me. Worth every penny.

Great Features
[This review was collected as part of a promotion.] Great set of nut drivers the magnetic feature is a must-have for almost all hand tools for hard-to-reach areas.

Great tool
[This review was collected as part of a promotion.] I like these nut driver set they work good for long bolt's

Very versatile
Having the pass through feature with a longer shaft is a very convenient perk. As has a hex patterned shaft to help torque down nuts. The only Con I have is the magnetic is so strong on the inside that it may come undone. My 7/16 drivers magnet came out but using some glue with have it back in action.

I bought these about a year ago as I was just starting out as an electrician and I use these multiple times a week on motors or threaded rod. Super versatile and dependable
