Astro Tool 78215 – 15-Pc 1/2" Drive Low-Profile Nano Impact Sockets (Metric)

Overview

The Astro 78215 15-piece set delivers a compact, high-strength solution for metric fasteners. Built from forged CR-MO steel with a precision finish, these nano impact sockets are designed to work in tighter spaces without compromising strength or reliability.

Key advantages

• 1.10 inch (28 mm) overall length, making them 37% shorter than traditional shallow sockets and 15% shorter than many stubby sets.
• 22 mm (7/8 inch) outside hex provides increased access when used with a wrench.
• Forged CR-MO construction with thicker walls for durability and a consistent fit between body and drive.
• Complete metric range from 10 mm to 24 mm with no skipped sizes.

Practical use and design

Ideal for automotive maintenance, equipment repair, and crowded mechanical bays, the low-profile geometry helps you reach fasteners behind components, panels, or in cramped engine compartments. The smooth machining and snug tolerances support reliable engagement and reduced cam-out during use.

The set’s compact profile also contributes to a lighter toolbox footprint, while maintaining a sturdy, metal-on-metal feel that many technicians appreciate during long jobs. While results vary by task, the sockets are designed to be a dependable option when space is at a premium.

Durability and care

CR-MO steel combines strength with resilience in impact environments. Store the sockets properly after use to protect the finish, and pair them with a compatible 1/2-inch drive impact wrench or ratchet for best results.
