3/8 in Drive 5/16 in Hex Socket

This Wiha Tools socket is a 12-point SAE hand tool made from alloy steel with a chrome finish. It features a 3/8 inch drive size and a 5/16 inch hex opening. The product meets ASTM F1505, CSA, EN/IEC 60900 and NFPA 70E standards. It is rated for insulated use and carries VDE certification.

Suited for insulated fastening work

This socket suits technicians who need an insulated hand tool for electrical applications up to the rated standards. It is not impact rated, so it should not be used with power impact drivers. Buyers who require impact-rated sockets or metric sizing should look at alternatives. The tool is restricted from sale in certain states due to Proposition 65 warnings.

Insulated to EN/IEC 60900 and VDE

The single specification that decides fit is the insulation rating to EN/IEC 60900 and VDE certification. This confirms the socket is tested for live working up to the standard voltage. Without this rating the tool would not be suitable for electrical safety tasks. Verify your required voltage class before purchase.

Questions about this item

Should I choose the 12-point 5/16 in socket or a different drive size?

This model is a 3/8 in drive, 5/16 in hex SAE socket with a 12-point profile; select it when that exact size and drive combination matches your fastener.

What does the ASTM F1505 and EN/IEC 60900 rating mean when I use this socket?

Those standards certify the socket for insulated work up to 1 000 V AC, so it is rated for live electrical tasks under NFPA 70E and VDE rules.

Is the 3/8 in drive compatible with my existing ratchet and torque tools?

Yes, the 3/8 in square drive fits standard 3/8 in ratchets, extensions and torque wrenches; the socket is not impact-rated, so use it with hand tools only.
