5.5 mm insulated socket

This Gray Tools socket is a 5.5 mm, 1/4 inch drive, 6-point tool insulated to 1000 V. It carries an orange outer insulation layer over a yellow inner layer that acts as a visual safety indicator. Each piece is individually tested to ASTM F1505 standards. The product is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

Professional electrical work only

The socket suits electricians and technicians who need verified 1000 V insulation on a 5.5 mm fastener. It is not for general mechanical use where insulation is unnecessary, nor for anyone requiring a different hex size or drive configuration. Buyers needing impact-rated or non-insulated sockets should look elsewhere.

1000 V insulation rating

The decisive specification is the 1000 V insulation rating backed by individual ASTM F1505 testing. This rating determines whether the socket meets the live-voltage protection required for the job. Without this certification the tool would not be suitable for energised electrical work.

Questions about this item

How can I confirm the 5.5 mm 6-point socket is still safe for 1000 V work after I start using it?

The yellow inner insulation layer becomes visible if the orange outer layer is damaged, giving an immediate visual cue that the 1000 V protection may be compromised.

What comes with the M605.5-I and what must I supply myself?

The package contains the single 5.5 mm insulated socket; a 1/4" drive ratchet or extension is not included and must be purchased separately.

Which Gray Tools insulated socket should I choose for a 5.5 mm fastener?

Select the M605.5-I — its 5.5 mm hex size and 6-point drive match that fastener exactly.
