Astro Pneumatic Tool 78344 Metric 3/8" Drive Nano Pinless Universal Impact Sockets (10Piece)

I recently completed a full front suspension job at home—inner and outer tie rods, brakes, struts, rotors, hubs, lower control arm, bushings, stabilizer bar, sway bar links, and more. For most of that work, I relied heavily on Astro swivel sockets, and they absolutely delivered. I originally used their 3/8” swivel sockets extensively with a high-torque 3/8” impact producing 500+ ft-lbs, and I did not go easy on them. After the job, the sockets still looked nearly new. The swivel action remained tight and controlled, holding position like OEM-quality tools. Compared to big-truck brands, these are easily a fraction of the price with no noticeable sacrifice in performance. Since then, I also purchased Astro’s new 1/2” drive mid-length pinless swivel socket set, and I’m equally impressed. The mid-length design is a perfect balance—long enough for access but compact enough for tight spaces. The pinless universal joint is smooth, strong, and confidence-inspiring, especially under impact use. The deeper hex engagement and clear, laser-etched + stamped size markings make these very practical for daily or heavy weekend use. They feel purpose-built for real suspension and drivetrain work. Important Update on the 3/8” Mid-Length Version Astro revised the 3/8” mid-length swivel sockets in September 2025 (newer version) after reports of failures related to additional weight. The updated version now includes: • A new retaining ring design • An improved ball swivel groove to prevent snapping Astro clearly listened to feedback and addressed the issue properly. The YouTuber EZtechJoe has more detailed technical information, as Astro contacted him directly regarding the revision. Because of this update, I’m now planning to purchase the new revised 3/8” mid-length swivel sockets as well. No Issues with Shallow Sockets For clarity, I’ve been using Astro’s 3/8” shallow swivel sockets for over a year with zero issues. They performed exceptionally well and were rated among the top 3/8” swivel sockets on the Torque Test Channel, which matches my real-world experience. Final Thoughts Astro continues to prove they offer excellent value, smart engineering, and real durability. These sockets work flawlessly in ratchets and impacts, fit where they need to, and hold up to serious torque. Between the shallow, mid-length, and revised designs, Astro swivel sockets are now a permanent part of my toolbox. Highly recommended.

Great medium-sized swivel sockets. Well-built and have stood up to the daily use I have put them through at an automotive repair shop. Since returning to the auto industry, I have bought several sets of sockets from Astro and I have been impressed with the quality. Plus, they are so much cheaper than the tool truck brands.

Astro Pneumatic makes very good impact sockets. They are much higher quality than their price tag represents. Sockets pivot freely without being too loose and a good selection of sizes. Organizer tray they come on is solid and makes storing them easy.

It was a toss-up between this and the Tekton set. Selected this one due to cost and the warranty. Tekton was just too expensive. Didn't want a "pinned" set and these were the answer. Astro makes good stuff and I saw the torque testing of these on YouTube and they were impressive. Wish it included 8 and 9mm but I'll buy those separate. Come with a nice rail too.

I have the same identical set except made by Snap-On and I have broken two of them. These Astro pinless swivel sockets beat Snap-On hands-down. They’re 1/5th the price and you cannot tell the difference in quality. What’s worse, is the Snap On rep does not want to replace the broken ones without me buying a whole new set. I'm just a car enthusiast, not a professional mechanic. I own several vintage automobiles and planes I need to keep in top shape. Astro Tools help me immensely. I’m done with Crap-On forever.

Every bit as durable, strong, and effective as Snap On swivels for a fraction of the cost. I use these daily at my shop and have done so for the last year with zero issues. They get abused pretty good, but still work flawlessly every time. Fit is great and they can grip nearly rounded fasteners easily.

Was suggesting this product by someone and I’m not disappointed good quality product and price is affordable…

Absolutely love these sockets. The quality is absolutely outstanding, along with their durability and I truly admire the design. Slimmer than most brands including Matco and Snap-On, not to mention much , much less than most generic tool truck brands. The slimmer design compared to others make those odd to reach areas easier to use, provide less headache, and genuinely save time.
