  • Insulated to 1000 V for live-circuit safety

Insulated 3/8-Inch Nut Driver

This Gray Tools CH12-I nut driver provides a 3/8-inch hex opening for fastener work. It is built for professionals who require verified electrical protection up to 1000 V during maintenance or assembly tasks. The tool meets ASTM F1505 standards for insulated hand tools.

Dual-Layer Insulation Upgrade

The driver replaces standard non-insulated nut drivers when live-circuit exposure is a risk. Its orange outer layer and yellow inner layer act as a visual safety indicator, revealing damage before the user contacts energised parts. The jump is worth it whenever 1000 V rated protection is specified.

Compatibility And Safety Checks

Verify that the 3/8-inch hex matches the fastener size required for the job. Confirm the insulated rating aligns with the voltage environment and that the cushioned non-slip handle suits the operator's grip preference. Check for Proposition 65 chemical warnings applicable to your region.
