11 mm 1000 V Insulated Socket
The Gray Tools MT11-I is an 11 mm, 3/8 inch drive socket with a 12 point profile. It is individually insulated and tested to ASTM F1505 standards for live-line work. An orange outer insulation layer covers a yellow inner layer that acts as a visual safety indicator. The assembly is rated for user protection up to 1000 V.
For Electrical Maintenance Professionals
This socket suits electricians and maintenance technicians who need certified insulation on fasteners energised up to 1000 V. The dual-colour insulation allows quick visual confirmation of coating integrity before each use. It is not intended for general mechanical work where insulated tooling is unnecessary, nor for applications requiring impact-rated drive tools.
11 mm Hex Capacity
The 11 mm hex opening fits standard metric fasteners in electrical panels, switchgear and terminal blocks. The 12 point drive engages the fastener at multiple angles for easier alignment in confined spaces. The insulation thickness required for the 1000 V rating adds bulk, so clearance around recessed or tightly spaced bolts should be verified before use.

Questions about this item
What drive size do I need on my ratchet or torque wrench to use this 11 mm socket?
The socket has a 3/8" drive, so you need a 3/8" square-drive ratchet, breaker bar or torque wrench.
Will the 12-point opening fit the 6-point fasteners already in my toolbox?
Yes, the 12-point drive engages both 12-point and standard 6-point bolt heads.
How can I verify the insulation is still intact before each job?
Check that the orange outer layer shows no yellow underneath; visible yellow means the insulation is compromised.
