Astro Nano 3/8-Inch Drive Impact Socket Set — SAE or Metric
Stubby forged chrome-moly impact sockets only 0.88 inch long for 3/8-inch drive work in cramped engine bays, suspension areas, and equipment. A 17 mm outside hex lets a wrench drive the sockets where a ratchet head will not fit.

QUICK ANSWERS
Common questions
How much space do they save?
Astro lists a 0.88-inch length and says that is 35% shorter than ordinary shallow impact sockets.
Can I use the outside hex with a wrench?
Yes. The sockets have a 17 mm outside hex for restricted-access work.
Do they work with the 78318 Nano ratchet?
Yes. Astro identifies the Nano-style 17 mm outside hex as the interface used by that ratchet system.
Should I buy SAE or metric?
