Insulated 3/8" Drive Socket Set

The Wiha 31590 set contains ten insulated pieces built for 3/8 inch drive tools. Eight 12-point metric sockets cover 8 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 17 mm and 19 mm sizes. Chrome vanadium steel with a chrome finish provides durability for hand-driven applications. This kit suits technicians who need insulated hand tools for electrical safety.

Hand-Drive Only, Not Impact Rated

The sockets are rated for hand drive use and are not impact rated. Bolt clearance is 7/16 inch, limiting the maximum fastener shank diameter that can pass through. No deep or flex sockets are included in the assortment. Users requiring impact-rated sockets or deeper reach must select a different set.

10-Piece Count With Eight Metric Sizes

The box delivers ten pieces total, but only eight are standard 12-point metric sockets. Buyers expecting ten distinct socket sizes will find two pieces are not standard sockets. Verify the exact contents match the fastener range required for the job.

Questions about this item

Which socket sizes come in the 10-piece 3/8" drive metric set?

The set includes eight 12-point sockets in 8, 10, 11, 12, 13, 14, 17 and 19 mm, plus an insulated ratchet and extension bar.

What does the 7/16 in bolt clearance mean when I am working on live equipment?

It shows the maximum bolt shank diameter that can pass through the socket, so you can reach nuts on longer threads without the bolt bottoming out.

Is the 3/8" square drive compatible with my existing insulated torque wrench?

Yes, the 3/8" hand-drive square fits any standard 3/8" drive tool, including insulated torque wrenches and ratchets.
