12 Piece Metric Box End Wrench Set
The Gray Tools M212R-I set contains twelve 12 point metric box end wrenches covering 8 mm to 17 mm. Each wrench carries a 1000V insulation rating for protection against electric shock. The orange outer insulation layer sits over a yellow inner layer that acts as a visual safety indicator.
Sustained load behaviour
The double layer insulation maintains its dielectric strength during continuous use on live circuits up to the rated voltage. High quality materials resist deformation when torque is applied repeatedly across the size range. The 12 point box ends engage fasteners securely to reduce rounding under steady force.
1000V insulation practical limits
The 1000V rating applies only when the insulation is intact and free from cuts, abrasion or chemical damage. The yellow indicator layer reveals compromise before the orange outer layer fails completely. California Proposition 65 warnings note the presence of chemicals known to cause cancer and reproductive harm.

Questions about this item
Does the 1000V insulation on these box end wrenches degrade from heat during all-day electrical work?
The set uses a double-layer insulation system with an orange top layer and a yellow inner layer that acts as a visual safety indicator; if the yellow layer becomes visible, the wrench should be removed from service.
What drive tools or accessories are required to use these 12-point metric box ends?
These are non-ratcheting box end wrenches sized from 8 mm to 17 mm, so they operate by hand without any drive tools, sockets or adapters.
Will the 12-point openings on this M212R-I set engage the older 6-point fasteners on my existing equipment?
Yes, the 12-point box ends fit both 12-point and 6-point metric fasteners across the 8 mm to 17 mm range, allowing use with older hardware.
