## Description

By popular demand, Astro introduces the 78318 Extra-Long Flex Head Nano Socket Ratchet Wrench! This 18” long 72-thooth flex-head ratchet features a c-ring retention design to allow low-profile Nano sockets to snap in and stay in, offering a slim 0.88” thick tool when paired with any Astro 3/8” drive Nano sockets and offerings from other brands that have caught on to this popular 17mm outside hex socket design. This means driving sizes all the way from 6mm to 24mm and every size in between when used with our 78319 6-24mm Nano socket set. As well as all SAE sizes as well. We made this one as long as our forging blanks could fit, 18” to access deep and difficult to reach bolts or just to provide that leverage you need on larger sizes, all while keeping your hands free.

Review: Astro tools are legit. This wrench for the low profile sockets is the best. Has an inner ring to lock the sockets in place and the handle so the right size. They haven't up sized the handle keeping the profile slim for those hard spots and with flex head. This won't be my last Astro tool buy, not by a long shot.
Review: Firstly, the quality is pretty strong. Its long handle makes it super easy to crack bolts or nuts. Slim head design can get through almost tight spaces. Perfect pair with Astro Tools 78319 socket set. No regret at all.

## Features

- Designed to work with and retain Astro Nano style stubby impact sockets (or other brands using our 17mm outside hex design) for a full working height of just 0.88”

- Complete 6mm to 24mm coverage with one tool by pairing with Astro 78319 6-24mm no skip set

## Questions & Answers

**Q: OK! get it together! so is this 72 tooth or 100 tooth?**
A: 100 tooth

**Q: Is it reversible or you just swap sides?**
A: Swap sides. It also has a retention ring on the 17mm, otherwise a ratcheting 17 will do the same thing...but shorter

**Q: Could they have a extra step and made it reversible?**
A: I don't know what you mean but it's reversible you just flip the wrench or the socket around.

**Q: Do they have one for their 22mm nano sockets?**
A: It works with all nano sockets 6mm to 24mm as long as they have the 17mm hex on them where a wrench would fit.
