Astro Nano 3/8-Inch Drive Pinless Universal Impact Socket Set — SAE or Metric
Low-profile universal impact sockets with a pinless joint that can angle and rotate through a full 360 degrees. Choose the 8-piece SAE set or 10-piece metric set for tight-access fasteners where a straight socket will not line up.

WHY IT WORKS
Why this product
Nano-Length Access
The reduced profile helps in spaces where a conventional universal socket assembly is too tall.
Impact-Ready Construction
Forged chrome-moly construction is intended for compatible powered impact use.
Choose One Measurement System
Separate SAE and metric sets keep the fastener fit clear.
CHOOSE WITH CONFIDENCE
Choose SAE or metric
- Choose the 8-piece SAE set for inch fasteners from 5/16 through 3/4 inch.
- Choose the 10-piece metric set for metric fasteners; verify the included range covers the sizes you service.
- Do not substitute the nearest SAE size on metric hardware, or the nearest metric size on SAE hardware.

COMPATIBILITY
Tool, angle, and fastener compatibility
- Use with a 3/8-inch square-drive impact tool within the tool and socket ratings.
- Keep the socket fully seated; extreme joint angles reduce efficient torque transfer and can increase wear.
- Confirm the Nano body still provides enough reach for recessed fasteners or long studs.
QUICK ANSWERS
Common questions
What is the advantage of a pinless universal socket?
The head can angle and rotate without the projecting pin found on some universal-joint designs, helping it work in confined spaces.
How do I choose between the two sets?
Order SAE for inch fasteners or metric for metric fasteners. The SAE set has 8 pieces; the metric set has 10.
Are these impact sockets?
Yes. Astro identifies them as forged chrome-moly impact sockets for compatible 3/8-inch drive tools.
Will they replace every standard socket?
No. Their strength is angled, low-clearance access; a straight socket is still preferable when the fastener is directly accessible.
