3/8 in Drive 9/32 in Hex Socket

This insulated socket is built for 3/8 in drive tools and fits 9/32 in hex fasteners. The 12-point alloy steel construction provides secure engagement on SAE hardware. It is manufactured by Wiha Tools and carries the model number 31428. The chrome finish adds corrosion resistance for workshop use.

Electricians and maintenance technicians

The socket suits professionals who work on live or potentially live equipment up to the rated insulation class. It is not designed for impact drivers, so mechanics who need impact-rated tools should look elsewhere. Buyers requiring a different drive size or metric hex dimensions will need a different socket.

Insulated to EN/IEC 60900

This single specification confirms the socket is tested and certified for electrical insulation according to EN/IEC 60900. It also meets ASTM F1505, CSA and NFPA 70E standards. Verifying this marking is the decisive step before using the tool on energised systems.

Questions about this item

Does the 3/8 in drive socket fit standard 3/8 in ratchets and extensions?

Yes, the 3/8 in drive square matches any standard 3/8 in ratchet, breaker bar or extension, so it drops straight into your existing socket rail or tray.

What is the common mistake when fitting the 12-point 9/32 in socket onto a fastener?

Users often confuse the 9/32 in size with the similar 7 mm metric socket; verify the SAE marking and engage all twelve points squarely before applying torque.

Will the chrome-alloy steel socket require periodic re-insulation testing under ASTM F1505?

The insulation is permanent for the socket's service life; ASTM F1505 does not mandate recurring dielectric tests, only replacement if the chrome finish shows cracks or wear.
