Astro Tools 78314 14-Piece 3/8" Drive Nano Impact Sockets – Metric | AP Astro Pneumatic Tool Company

Overview

Introducing the Astro Tools 78314 14-piece metric nano impact socket set for a 3/8 in drive. Precision broached forged CR-MO delivers durable performance in a compact form. At 0.88 in (22.5 mm) long, these sockets sit 35 percent shorter than shallow options and 15 percent shorter than typical stubby sets, opening up access where space is tight.

Smart design for tight spaces

Each socket features a 17 mm outside hex, engineered to improve access when used with a wrench. That design detail can make it easier to grip and turn fasteners in cramped engine bays, under dashboards, and other confined areas.

Material and build quality matter. The sockets are forged from CR-MO with carefully engineered wall thickness between the socket body and drive, helping resist wear and deformation during repeated use.

What’s included and how it fits your toolkit

• 14 metric sockets for 3/8 drive
• Low-profile length enhances clearance in tight spots
• Durable CR-MO construction with optimized wall thickness

In practice

Picture routine maintenance on modern cars, motorcycles, or compact machinery where space is at a premium. The nano sockets enable you to reach recessed fasteners without contorting your hand or swapping tools, pairing well with common ratchets and impact drivers in automotive and gear projects.

Tips for best results: use with compatible torque tools when appropriate, and store with other metric sets for quick access in crowded toolboxes. The compact profile keeps your kit lighter while preserving grip and torque transfer.
