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.

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.

You can tell from the photo that I don’t need any extra sockets. This set fits into the ratchet and makes it more low profile, a lot like a ratchet wrench only a little thicker. I’ve used the long leverage couple of times and the ratchet has held up. I don’t abuse it, but I do put it to work. I love the set would definitely recommend it. When you need it for the right spot it’ll pay for itself.

Absolutely love this set. Got the 19pc 6mm-24mm so great rage in sizes. Low profile, impact rated and the price is on point. Great set of sockets .

Some of the best sockets I've bought as a automotive technician these are literal life savers! Would definitely recommend to young techs getting into the industry

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.

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