16 mm Insulated Socket

The Gray Tools MT16-I is a 16 mm, 3/8 inch drive socket with a 12 point configuration. It is designed for electrical work where protection up to 1000 V is required. The tool suits professional electricians and maintenance technicians.

ASTM F1505 Test Standard

Each socket is individually insulated and tested to ASTM F1505 standards. An orange top insulation layer covers a second yellow layer that acts as a visual safety indicator. Damage to the orange layer reveals the yellow beneath, signalling that the insulation integrity may be compromised.

1000 V Protection Limit

The insulation provides user protection for up to 1000 V in live-line applications. It is not suitable for voltages exceeding this rating. The socket handles standard 16 mm fasteners, but offers no headroom for higher-voltage environments.

Questions about this item

Which drive size matches the 16 mm hex on this socket?

The socket has a 3/8 inch drive, so it fits any 3/8 inch ratchet or breaker bar you already own.

What does the 1000 V rating mean when I am working on live circuits?

Each socket is individually tested to ASTM F1505 and the orange-over-yellow insulation protects you up to 1000 volts AC.

How does the 12-point drive engage the fastener compared with a 6-point?

The 12-point geometry gives twice as many engagement positions, letting you turn a 16 mm bolt in tighter swing arcs.
