Professional socket for automotive work

The Wiha Tools 31811 is a 3/8 inch drive socket with a 5/16 inch SAE hex bit. Six-point geometry provides strong grip and maximum torque transfer on fastener flats. It suits technicians who need reliable engagement on stubborn bolts. The alloy steel construction resists rounding under high load.

Urethane insulation prevents heat transfer

Colour-coded urethane coating covers the metal body so hands stay comfortable during extended use. The insulation blocks heat moving from the socket to the user's grip. Chrome finish adds corrosion resistance in workshop environments. Overall length measures 3 7/64 inches for access in standard depths.

California Proposition 65 notice applies

The product carries a Proposition 65 warning for chemicals linked to cancer and reproductive harm. No additional accessories or software are included in the package. Buyers needing insulated sets or metric sizes must source them separately. The single socket ships ready for immediate use.
