Astro Tools 78319 19pc 3/8" Drive 6-24mm Low Profile Nano Impact Socket Set - No Skips

The Astro Tools 78319 Nano Impact Socket Set has quickly become one of my favorite tool purchases. The low-profile design is a game changer when working in tight engine bays, suspension components, and other hard-to-reach areas where standard impact sockets simply won't fit. The quality of the sockets is excellent. They feel solid, well-machined, and have held up perfectly under repeated use with both impact wrenches and ratchets. The black finish is durable, and the size markings are easy to read even after getting covered in grease and dirt. One of the biggest advantages of this set is the complete range from 6mm to 24mm with no skipped sizes. It's incredibly convenient not having to search for a missing size or buy additional sockets separately. The compact storage rail also keeps everything organized and easy to access. The reduced height doesn't compromise strength, and the sockets grip fasteners securely without slipping. I've used them on automotive repairs ranging from brake jobs to engine work, and they've performed flawlessly. If you're a professional technician or a serious DIY mechanic, this set is absolutely worth adding to your toolbox. The combination of durability, low-profile access, and complete size coverage makes it an exceptional value.

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!

Works great in tight places on cars. Great addition for the toolbox will get used

Amazing quality, all sizes fit properly, rail is beautiful anodized aluminum and extremely sturdy. The sizes are clearly labeled twice, one silk screen size and one engraved... Already filled in the engraved section just for easier viewability. Best bang for your buck on a non skip size... beautiful broaching and the size of the hex at the base fits a 17mm ratcheting wrench for those impossible to reach spots with a regular ratchet. All in all, one of the best purchases I've made on Amazon to date.

Excellent quality and price. Works perfectly with the Astro ratchets.

Used this set on my 2017 Chrysler Pacifica while replacing the idler pulley, and they absolutely did the trick. Clearance was super tight and a standard socket would’ve made it a fight. Paired these with the Astro 78318 extra-long flex head nano ratchet and it was the perfect combo. The low profile height is what makes these special — they let you get into spots where a normal 3/8” socket just won’t fit. No rounding, solid engagement on the bolt, and they feel well made — not gimmicky thin. If you’re working on modern vehicles where everything is crammed into the engine bay, these are worth owning. This is one of those specialty tools that actually earns its space in the drawer. Glad I picked them up.

I compared several 17mm sockets, and I’m impressed by how low-profile these are. The compact design makes them ideal for working in tight spaces. However, due to the thinner wall compared to standard impact sockets, I do have some concerns about long-term durability when used with an impact wrench. The overall fit and finish are excellent, and they feel solid in hand. One thing I did notice: there’s a noticeable difference in surface finish between the 5mm–16mm range and the 17mm–24mm sizes. Not a major issue, but worth noting.

Excellent set of flat sockets, very useful in places that are difficult to access.

Good quality and small enough to fit inside small spaces where tradition sockets wont go. This is my first purchase from Astro tool and I am really impressed with the product so far.

Thanks

sin duda una excelente inversión. riel de aluminio y dados metricos desde 6 hasta 24. los dados traen cuadro para usarse con matraca convencional. es superior en cuanto alcance y espacio reducido. el maneral 78318 sujeta al dado muy seguro. en la imagen la comparación con matraca 3/8 bajo perfil y dado craftsman10mm.

Good stuff,good material as per description
