## Overview

The Astro Tool 78318 Extra-Long Flex Head Nano Socket Ratchet Wrench is an 18-inch, flex-head ratchet designed for tight and hard-to-reach hardware. Featuring a 100-tooth mechanism for smooth operation and a slim 0.88-inch profile when paired with Nano sockets, it offers full 6mm to 24mm size coverage. Its c-clip retention system securely holds low-profile Nano sockets, making it ideal for modern, compact engine bays and demanding mechanical tasks.

## 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: This Ratchet Is the Real Deal in Tight Spots - Bought this specifically to pair with the Astro nano sockets, and it paid off immediately. Used it on my 2017 Chrysler Pacifica doing an idler pulley. Clearance in that area is tight and awkward. The extra-long handle gave me the leverage I needed, and the flex head let me dial in the exact angle without fighting the frame or other components. Combined with the nano sockets, this setup is money. The low profile plus the slim head design makes it way easier to work in modern engine bays where everything is packed in. It feels solid, not sloppy. The mechanism is smooth and the length actually helps instead of getting in the way. If you work on your own vehicles and run into tight clearance issues often, this ratchet + nano socket combo is worth it. It’s not a gimmick tool — it actually solves a problem. Glad I added it to the drawer.
Review: Quality and compact with the lenght you need - I've always used a 17mm ratchet wrench with nano sockets. Now breaking my 3rd sears wrench I decided to try this one and what I love about it is the swivel. so far it's great and can get into tight places better than I thought. My e 400 has bolts 18mm rear 89 ft lbs caliper brackets that you cannot use a socket and this works perfect to break free then use 18mm wrench to remove it. You cannot beat it for the price. Plus you have the extra 17mm wrench for more versatility as its very long. Plus lifetime warranty.

## 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 Ratchet Is the Real Deal in Tight Spots

### ⭐⭐⭐⭐⭐ Outstanding Long‑Reach Nano Ratchet—Perfect for Astro/CROM Sockets
*by P***W on May 9, 2026*

This Astro 78318 Extra‑Long Flex Head Nano Ratchet is one of those tools you don’t realize you need until you use it—and then it becomes indispensable. If you run Astro or CROM 17mm nano sockets, this ratchet is made for them. The built‑in retaining ring snaps the nano sockets in securely so they stay put until you intentionally remove them. The flex head and extra‑long handle give you the reach and leverage needed for fasteners buried deep in engine bays or tucked behind brackets. Just remember it’s still a 3/8" ratchet, so you can over‑torque it if you’re careless. That said, Astro backs their tools with a lifetime warranty, and they’ve always stood behind their products. The ratchet is made in Taiwan, and the build quality reflects that—tight tolerances, smooth action, and a solid feel. To reverse direction, you flip the ratchet over; the side with the Astro branding is the tightening (ON) side. A small improvement would be an arrow indicating direction, and a bigger upgrade would be a built‑in reversing switch like you see on Gearwrench or Matco nano ratchets. Interestingly, you can give this ratchet that capability: the Matco head assembly repair kit fits this tool, adding a reversing switch. Even after buying both the Astro ratchet and the Matco head, the total cost is still about half the price of the full Matco equivalent. I left my 18" version stock because the 100‑tooth (3.6°) mechanism is excellent, but I did convert the smaller 10.5" version using the Matco kit (which is 72‑tooth). Overall, this is a fantastic long‑reach nano ratchet—strong, smooth, compact, and incredibly useful. I highly recommend it.
