Gray Tools V110-I 5/16" 1/4" Drive 12 Point 1000V Insulated Socket

SKU CH-8J02-X1J83

A 5/16" 12-point insulated socket with dual-colour safety layers tested to 1000 V and ASTM F1505 standards

  • 1000 V protection with dual-layer orange and yellow insulation
  • 12-point drive engages hex fasteners from multiple angles
  • Individually tested to ASTM F1505 safety standard
  • Yellow inner layer acts as visual wear indicator
  • 5/16 inch hex size fits common automotive hardware

Socket Specification

This 12-point insulated socket fits a 5/16-inch hex fastener and accepts a 1/4-inch drive. It is built for electricians and maintenance technicians who work on live circuits up to 1000 volts. The orange outer insulation and yellow inner layer act as a visual safety indicator during use. Each piece is individually tested to ASTM F1505 standards.

Pre-Installation Checks

Verify that the fastener hex size matches 5/16 inch and that your ratchet or torque wrench has a 1/4-inch square drive. Inspect both insulation layers for cuts, cracks or colour wear before every job. Confirm the work environment does not exceed the 1000 V rating marked on the tool. Ensure the socket sits fully on the fastener to avoid slippage under load.

Sustained Load Behaviour

The dual-layer insulation maintains its dielectric strength during prolonged contact with energised components. The 12-point geometry distributes torque evenly across the fastener flats, reducing rounding risk during extended tightening cycles. The yellow indicator layer remains visible to signal insulation integrity throughout the task. The socket retains dimensional stability under continuous mechanical stress.

Questions about this item

What comes with the V110-I insulated socket and is any extra tool needed?

The socket is sold individually with its dual-layer orange and yellow insulation. A 1/4" drive ratchet or extension is required to turn it and is not included.

How do I choose between the available versions of this 1000 V insulated socket?

This model is a single 5/16" hex, 12-point, standard-length socket. No other sizes or lengths are offered under the V110-I part number.

What does the 1000 V rating mean when I am using the socket on live equipment?

Each socket is individually tested to ASTM F1505 and rated for 1000 V AC/DC. The yellow inner layer shows through if the orange outer insulation is damaged, signalling replacement.
