Overview
Sized at 19mm and built from chrome vanadium steel, the MTO MTO-CR-V-DEEP-19mm is a single deep wrench rather than part of a set. The CR-V code in the model name spells out the material, and the deep designation points to a reach built for longer bolts.
Chrome vanadium is a common choice for hand tools because it resists wear and flexing better than plain carbon steel, and the deep designation in the name suggests a deep socket or wrench profile built to reach over long bolts or studs. Beyond size and the single piece count, no further dimensions are listed.
- 19mm size
- Chrome vanadium (CR-V) steel
- Deep profile design
- Sold as a single piece
Who it's for
Useful for anyone who needs to fill a single 19mm gap in an existing socket or wrench set rather than buy a full new set. Not a fit for someone who needs a complete range of sizes in one purchase.
Strengths and trade-offs
Drawn from this product's published specifications.
- Chrome vanadium steel construction
- Deep profile for reaching over long bolts
- Sold as a single piece, not a set
- Exact depth and length are not listed
Performance notes
Chrome vanadium steel is chosen in hand tools for its resistance to bending and wear under torque, which matters most when breaking loose a stuck 19mm fastener. The deep profile suggested by the name should let it reach over longer bolts or studs than a standard depth wrench, though exact depth is not listed.
