Exceptional Nano Impact Socket Set – Little Sockets, Big Performance!
I recently added the Astro Tools 78314 14‑piece 3/8″ drive nano impact socket set to my toolbox, and I couldn’t be more impressed. These compact sockets pack remarkable power and versatility, delivering performance you’d expect from full-size sets—with a tiny footprint. 🔧 Why I love it: • Ultra‑low profile design: At just 0.88” (22.5 mm) long, they’re about 35% shorter than traditional shallow impact sockets and 15% shorter than other stubby nano options—perfect for tight engine bays and cramped spaces. • Rugged CR‑MO construction: Forged from chrome‑molybdenum steel with thicker walls than competitors, these feel robust enough for serious torque without cracking. • 17 mm outside hex feature: Makes it easy to turn with a wrench when a ratchet alone isn’t enough. • Professional-grade value: Comparable to bigger brands like Ko‑Ken at a much friendlier price—without sacrificing quality. 👍 Standout real-world results: • Got me into sub‑tight areas that used to require extensions or awkward angles—now, it’s a straight shot. • Handles high torque applications with zero deformation—haven’t had a single rounded stub. • All 14 sockets cover my typical metric needs, and the included aluminum holder keeps them secure and organized. ⸻ Bottom Line: If you’re a professional mechanic or a DIY enthusiast working in tight, torque-demanding areas, the Astro Tools 78314 nano impact socket set is a game-changer. It’s compact, tough, well-designed, and excellent value. Highly recommended!

Great tools from Astro. Must have in any mechanics box
Love the astro nano line. Working full time as an automotive technician these are a great tool to have in your box. Low profile for tight spaces and the pass through design of the sockets is great for removing nuts from studs without a deep socket or wrench. The swivel on the rachet are also very nice allowing even more maneuverability. The rachet itself has a great action and is smooth. Could be finer, but that sacrifices strength and these have held up to some serious torque. The sockets also have a standard drive socket on them as well and can be used with a standard rachet or on an extension which I have found extremely useful on multiple occasions due to the slim profile. Highly recommend!

Good quality.
Very solid and very low profile sockets. Has laser etched sizing and logo as well as stamped sizing in very, very small stamping but very legible too once you find it. Also comes with very nice aluminum socket rail that holds the sockets great and releases them without fighting them off the rail. Rail is very smooth and you can move the sockets side to side with little, if any effort at all. Astro Pneumatic makes good tools for the price.

Great set and love the low profile
★★★★★ Outstanding Low-Profile Socket Set – A Must-Have for Tight Spaces The Astro Tools 78319 19pc 3/8" Drive Low Profile Set is absolutely fantastic. The build quality is solid, the sockets feel durable, and the low-profile design makes a huge difference when working in tight or awkward spaces. I’ve already used this set on a few projects where regular sockets couldn’t fit, and it performed flawlessly every time. The sizing range from 6–24mm is perfect, and everything stays organized in the case. This set has quickly become one of my favorite tools in the box—highly recommended!

Excellent stubby socket set
Excellent set to go with the ratchet especially no skip in sizes. Excellent finish to the sockets and also comes with handy rail great price would definitely recommend buying if you haven’t going to get 1/4 & 1/2 set soon

Quality sockets great price.
Quality low profile sockets works great with a ratchet or the low profile ratchet tool that's made for the sockets.

Great, but don’t use with impact!
These are amazing for tight spaces, especially with the ratchet to go with it. I don’t recommend using with an impact. I let a buddy borrow the 24mm and it cracked on the corner by the anvil slot. I filled the warranty out on their website and they sent a new one. They replied quickly and shipped a new one, but the delivery time was a little slow.

Very useful sockets
Hugh quality sockets, very versatile in use. Very easy to use as most sockets are. They function very well, being able to get into tighter spots then most sockets can get into. 5/5 stars so far, size range is nice as well. Very useful when needed.
