  • 19 mm hex fits common fasteners

  • tested to ASTM F1505 for verified safety

Socket specification

The Gray Tools MT19-I is a 19 mm insulated socket with a 3/8 inch drive and 12 point geometry. It is built for electricians and maintenance technicians who work on live low voltage equipment up to 1000 V.

Upgrade path

This socket replaces standard chrome or non insulated sockets that expose the user to shock risk on energised panels. The jump is worth it whenever a job requires verified insulation rather than a makeshift cover or tape.

Sustained use

The orange outer layer and yellow inner layer act as a visual safety indicator that reveals damage before the insulation fails. Each piece is individually tested to ASTM F1505 so the protection remains reliable through repeated daily use.

Questions about this item

What drive size fits the 19 mm 12-point socket?

The socket has a 3/8 inch drive, so it fits any standard 3/8 inch ratchet or torque wrench.

How do you confirm the insulation is still safe before each use?

Check that the yellow inner layer is completely covered by the orange outer layer; if yellow shows through, the socket must be replaced.

When should the socket be replaced instead of reused?

Replace it once the orange insulation is damaged enough to reveal the yellow indicator layer, as this signals the 1000 V protection is compromised.
