Insulated 12-Point Socket

This 12-point socket fits 7/16" hex fasteners and accepts a 1/2" drive. Each piece is individually insulated and tested to ASTM F1505 for work on live circuits up to 1000 V. The dual-colour insulation uses an orange outer layer over a yellow inner layer that acts as a visual wear indicator. It is built for electricians and maintenance technicians who need verified dielectric protection.

Upgrading from Uninsulated Sockets

Standard chrome sockets have no dielectric rating and must not be used on energised equipment. This socket replaces them when a task requires 1000 V insulation and a visible damage indicator. The jump is worth it whenever the job site demands ASTM F1505 compliance and the ability to spot insulation wear at a glance.

Capacity and Headroom

The 7/16" opening handles that single fastener size across electrical panels, switchgear and motor terminals. The 1000 V rating covers common low-voltage industrial and commercial systems. It runs out when the fastener differs from 7/16", when the drive must be larger than 1/2", or when the system voltage exceeds the 1000 V test limit.

Questions about this item

What drive size does the 7/16" hex socket require?

The socket uses a 1/2" drive square, so it fits any standard 1/2" drive ratchet or breaker bar.

How do I install the socket on the ratchet, and what is the common mistake?

Push the socket onto the 1/2" drive anvil until the detent ball clicks; the error is stopping before the click, which lets the socket fall off under load.

When should the insulated socket be replaced?

Replace it if the orange outer layer is damaged enough to show the yellow safety layer beneath, because the 1000 V insulation rating depends on both layers being intact.
