4.5 mm Insulated Socket

The Gray Tools M604.5-I is a 4.5 mm hex socket with a 1/4 inch drive and six-point geometry. It is built for professionals who need insulated hand tools when working on live electrical systems up to 1000 V.

ASTM F1505 Test Standard

Each socket is individually tested to ASTM F1505 standards for insulated hand tools. The double-layer insulation uses an orange outer layer over a yellow inner layer that acts as a visual safety indicator if the outer layer is damaged.

4.5 mm Hex Size

The 4.5 mm hex opening determines fastener compatibility; this socket fits only that exact size. Buyers who need different hex dimensions or a different drive size must select another socket.

Questions about this item

Which socket size should I choose for a 4.5 mm fastener?

The M604.5-I is a single 4.5 mm hex socket, so it matches that exact fastener size without any other capacity options.

What does the 1000 V insulation rating mean when I am using the socket?

It means each socket is individually tested to ASTM F1505 and provides user protection for live work up to 1000 volts.

How does the 1/4 inch drive interface limit what I can use this socket with?

The 1/4 inch square drive only fits 1/4 inch drive ratchets, extensions and torque wrenches, so larger drive tools will not connect.
