1/4 in Drive 9 mm Insulated Socket
This Wiha Tools 31330 socket fits a 1/4 inch drive and a 9 mm metric fastener with a six-point profile. It is made from alloy steel with a chrome finish and meets ASTM F1505, CSA, EN/IEC 60900, NFPA 70E and VDE standards for insulated hand tools. The product is new and ships from the supplier.
Insulation Standards Change Safe Work
The VDE and EN/IEC 60900 markings mean the socket is tested for live working up to the rated voltage. ASTM F1505, CSA and NFPA 70E compliance adds further confidence for electrical maintenance. These certifications replace an uninsulated socket in any task where shock protection is required.
Hand Drive Installation Is Simple
The 1/4 inch square drive slides onto any compatible ratchet or extension without adapters. Because the socket is not impact rated, it must be used with hand tools only; power or impact drivers can damage the insulation and the alloy steel body. California Proposition 65 warnings note chemicals linked to cancer and reproductive harm.

Questions about this item
Will the chrome finish on this 9 mm socket need re-plating after heavy use?
The chrome coating protects the alloy steel from corrosion; it does not require scheduled re-plating under normal hand-tool use.
What stops me from using this 9 mm socket on an impact wrench?
The socket is not impact rated, so repeated hammer blows will crack the 6-point drive walls.
Does the insulated 1/4 in drive socket get hot during continuous fastening?
The insulation is rated to ASTM F1505 and IEC 60900 for electrical protection, not for thermal dissipation; the alloy steel body will warm with friction like any hand socket.
