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

Strong, good quality. Use with impact gun.

Great quality well made good for tight spots at back of engine

I have used these sockets for long enough now to say they are very durable compared to other brands. These are not the highest quality but would not recommend buying any other swivel sockets in terms of value for money.

Purchased to replace a smaller set with wide collars around the base. These are much narrower and have better access. They pair well with my M12 stubby impact, and have seen daily use at a heavy equipment dealership

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.
