1/4" Drive 9/32" SAE Hex Socket

The Wiha 31339 is an insulated 6-point socket made from alloy steel with a chrome finish. It meets ASTM F1505, CSA, EN/IEC 60900, NFPA 70E and VDE standards for electrical work. The 1/4 inch drive fits standard hand ratchets and extensions for general fastening tasks.

Insulated Design and Standards Compliance

The insulation allows use on live circuits up to the rated voltage defined by the listed standards. Alloy steel construction provides strength while the chrome finish resists corrosion. The 6-point profile grips hex fastener flats to reduce rounding during high-torque applications.

For Electricians and Maintenance Technicians

Suited for professionals requiring VDE-certified hand tools for panel work and equipment servicing. Not intended for impact drivers or pneumatic tools due to the hand-only rating. Buyers needing impact-rated sockets or metric sizes should look at other options.

Questions about this item

Does the insulated coating on this 1/4 in drive socket wear down and need replacement?

The insulation meets ASTM F1505, CSA, EN/IEC 60900, NFPA70E and VDE standards. Inspect it before each use; replace the socket if the coating shows cracks, cuts or abrasion.

What stops me from using this SAE socket on high-torque impact jobs all day?

The product is not impact rated. It is designed for hand use only, so sustained high-torque impact work will damage the alloy steel body.

Does the chrome finish get hot or make the tool slippery during extended use?

The chrome-plated alloy steel runs at ambient temperature in normal hand operation. The finish resists corrosion and wipes clean, maintaining grip without generating noticeable heat.
