1/2" Drive SAE Socket

The Wiha Tools 31720 is a 12-point socket with a 1-1/8 inch opening and a 1/2 inch drive. It is made from alloy steel with a chrome finish for hand-tool use in professional and industrial settings.

Insulated to EN/IEC 60900

This socket meets ASTM F1505, CSA, EN/IEC 60900 and NFPA70E standards for insulated hand tools. It carries VDE certification and is not impact rated, so it is intended for controlled manual torque only.

Single 1-1/8" Hex Opening

The socket fits exactly one SAE fastener size, making it the right part only when that specific hex dimension is required. Buyers needing multiple sizes or impact-rated sockets should look elsewhere.

Questions about this item

How do I install the 1/2 in drive socket onto my ratchet, and what step is often missed?

Align the square drive on the socket with the ratchet anvil and press until the detent ball clicks into the socket groove; the step often missed is verifying the ball is fully seated before applying torque.

What maintenance or replacement will the 12-point alloy steel socket need later?

Inspect the chrome finish and 12-point geometry for rounding or cracks after heavy use; replace the socket if the drive square shows deformation or the wall thickness is visibly reduced.

What limit appears first when the VDE-insulated socket is used continuously under load?

The insulation integrity is the first limit; sustained high current or heat can degrade the ASTM F1505, CSA and EN/IEC 60900 rated coating, so stop use if the surface shows discoloration or cracking.
