AP Astro Pneumatic Tool 78319 – 19-Piece 3/8-inch Drive Nano Impact Socket Set (6-24mm) – Low Profile, No Skips

Compact power for tough access

The Astro Tools 78319 19-piece set is built for 3/8-inch drive impact wrenches and Astro Nano low-profile ratcheting wrenches. Designed to slip into tight spaces, it helps you reach fasteners that standard sockets can miss. The result is a more efficient workflow in crowded engine bays, dashboards, and compact equipment where space is at a premium.

At a slim 0.88 inches (22.5 mm) in length, these sockets sit 35 percent shorter than shallow impact sockets and about 15 percent shorter than typical stubby sets. The reduced profile makes it easier to align the wrench with the fastener, especially when you are working in tight confines or awkward angles. With less bulk, you can maintain better line of sight and control during torque application.

Each socket features a 17 mm outside hex, a design choice that improves wrench engagement and minimizes slipping when you are maneuvering around obstacles or adjacent components. This consistency across the set helps reduce fiddling and increases confidence during repeated turns in restricted spaces.

The CR-MO forged construction brings durable performance to daily shop tasks. The thicker walls between the socket body and drive contribute to a robust feel under load, giving you the assurance you need when dealing with stubborn fasteners. While no product can guarantee outcomes in every scenario, the material and geometry are tailored to resist wear and maintain grip across a wide range of sizes.

Real-world usefulness and pairings

In practical use, the 6-24 mm range covers many common automotive and machinery fasteners, making it a versatile choice for shop staples and service jobs. Pair these sockets with Astro Nano low-profile wrenches for quick, controlled turns in tight layouts where a full-size kit would be cumbersome. The compact set also travels well in tool bags, service carts, or roll-up organizers, keeping essential sockets accessible without crowding your workspace.

• Full range 6-24 mm coverage for everyday automotive and equipment tasks
• Low-profile length reduces interference with nearby parts
• 17 mm outside hex on every socket for easier wrench engagement
• CR-MO forged construction with thicker interior walls for durability

As you plan tasks, think of this set as a possibility rather than a guarantee. It offers potential time savings, better access, and a compact footprint that helps you stay organized on the job. Whether you are performing routine maintenance or tackling a tight spot repair, the Nano sockets are designed to support efficient, confident work in constrained spaces.

• Possible improvements in access and speed when working in cramped areas with compatible tools
• Durable construction aims to withstand busy shop environments over time

If your projects demand a compact, capable set that respects space without sacrificing performance, the Astro Tools 78319 is worth considering as part of your go-to 3/8-inch drive toolkit.
