## Overview

The Astro Tool 78318 is an 18-inch extra-long flex-head ratchet wrench designed for professional-grade access to hard-to-reach hardware. Featuring a 100-tooth ratcheting mechanism and a slim 0.88-inch profile when paired with Astro Nano sockets, it offers smooth, precise operation and full 6mm to 24mm socket compatibility. Its c-clip retention system ensures secure socket fit, while the flex-head design provides versatile angle access, making it an essential tool for reducing bulk and increasing efficiency in any mobile toolkit.

## 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: Great tool when used as part of the overall system - Super impressed with this wrench, and the overall system as a whole. The wrench is super smooth, and the articulating head lets you use it in spots you wouldn’t be able to use a traditional straight wrench. Overall I love the wrench combined with the nano sockets. I can essentially carry the Astro ratcheting wrench combined with the nano sockets and replace both a ratchet and socket set as well as a traditional set of wrenches. This allows me to cut down on some of the weight in my mobile tool kit. I’ve used them on a few jobs so far, and they’ve allowed me to get into spots that I would have struggled with previously.
Review: Home run from Astro!! - Astro is a tried and true brand, and this is nothing short of a home run from Astro!! Astro makes great middle of the road tools for both diy'ers and pros. This is long overdue from astro and finally we get a long, nano socket compatible, flex head ratchet, with a super thin profile. I am extremely satisfied with this item and like most of astro's product line, it is very well priced, and affordable. This thing is beyond awesome!! I have quite a few astro tools in my lineup and I have never been disappointed, and this tool is no different. I can't say enough good things about this tool and I'm excited to get to wrenchin' with it!! If your on the fence about this tool, dont be, its worth every penny, and then some!! I seriously hope they come out with a version for their 1/2" nano set, or maybe even a 9" or 10" version, so you can get in closer quarters with the same low profile advantages. Astro is dropping some super fire new tools this year!! You should check out the astro 78354 10-Piece torque saver set. It's a 10mm-19mm no skip set and it is the EXACT SAME set that matco sells in 2 separate sets for over $600!! I don't mean it's like the matco set, I mean it's the EXACT SAME set that matco sells. Check it out!! ****UPDATE**** During November's 2023 SEMA show, Astro Pneumatic had on display some new and upcoming versions of this nano socket compatible flex head ratchet. They had several different sizes in the prototype stage that included a version that was medium length, and another version that was a short length version of this tool as well. Astro's booth had some absolutely killer new products this year that are in the production and protype stages scheduled for production in the near future. Astro is seriously killing it this year, and is thinking outside the box. They are coming out with some phenomenal new products. I'm excited for the release of the other versions that they had on display. These things are extremely popular, selling out twice since July of 2023. I grabbed 2 in case I break my other one because you can't warranty a tool you don't have in stock lol.

## 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.

### ⭐⭐⭐⭐⭐ This one surpassed my expectations entirely.
*by A***A on December 19, 2025*

The extended length is perfect for reaching those awkward, hard-to-access spots, and the flex head offers just the right amount of movement without feeling loose or unstable. It's clear a lot of thought went into the design, and it shows in how well it performs. Honestly, it’s rare to buy something that actually matches the description and delivers on its promises, but this does that and more.
