1/2 in Drive 22 mm Insulated Socket

This Wiha Tools 31622 socket fits a 1/2 in drive and provides a 22 mm metric opening with a 12-point profile. It is manufactured from alloy steel with a chrome finish and meets ASTM F1505, CSA, EN/IEC 60900, NFPA70E and VDE standards for insulated hand tools. The socket is rated for standard hand use and is not impact rated. It is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

Sustained load behaviour

Under continuous hand torque the alloy steel body and chrome finish maintain dimensional stability and corrosion resistance. The 12-point geometry distributes force across the fastener flats to reduce rounding during prolonged tightening or loosening cycles. Insulation integrity is preserved when the tool is used within its rated voltage limits and inspected for damage before each session. The socket is not designed for impact drivers, so sustained percussive loads will cause premature failure.

Upgrade path and fit

This socket replaces a worn or non-insulated 22 mm 1/2 in drive socket where electrical safety standards are required. The jump is justified when working on live or potentially energised equipment up to the tool’s rated voltage and when compliance with ASTM F1505, CSA, EN/IEC 60900, NFPA70E or VDE is mandated. It does not suit applications needing impact-rated sockets or drive sizes other than 1/2 in.

Questions about this item

Does the 1/2 in drive 22 mm socket generate noticeable heat during extended use?

No, it is a hand-operated insulated socket with no moving parts or electrical load, so it produces no heat during normal operation.

What drive tool is required to use this 22 mm 12-point socket?

A 1/2 inch drive ratchet, breaker bar or torque wrench is needed to engage the socket's square drive.

Will this ASTM F1505 and IEC 60900 rated socket fit older 1/2 in drive handles I already own?

Yes, the 1/2 inch square drive conforms to standard dimensions, so it works with any compatible 1/2 in drive handle regardless of age.
