Overview
DuraTech's CR-V wrench carries a listed weight of 1.05 kilograms under Tools > Wrenches, more than a single hand tool typically weighs.
CR-V refers to chrome vanadium steel, a common alloy for wrenches valued for its balance of hardness and flex resistance. At roughly 2.3 pounds total, this is heavier than one wrench typically weighs, which points toward a set rather than a single piece, though an exact count is not stated in the data.
- 1.05 kilogram total weight
- Chrome vanadium (CR-V) steel
Who it's for
Buyers wanting a chrome vanadium wrench tool with active recent sales may find this fits. Anyone who needs an exact size list confirmed before ordering should verify piece count and sizes directly, since that detail is absent here.
Pros and cons
- Chrome vanadium steel construction
- Piece count not specified
- Individual wrench sizes not listed
Performance notes
Chrome vanadium steel resists bending under torque better than plain carbon steel, which is why it shows up often in wrench construction. The listed weight of 1.05 kilograms is consistent with either one heavy duty wrench or several smaller ones combined, and the data does not distinguish between the two.
