Overview
A three piece all steel adjustable wrench set from Craftsman, model CMMT12001, covering 6, 8 and 10 inch sizes with a chrome finish. Backed by Craftsman's lifetime warranty.
Adjustable wrenches trade the exact fit of a fixed wrench for the ability to cover a range of bolt sizes with one tool, which is why a three piece set spanning three lengths is more useful than a single wrench alone. Wide jaw opening and clear size markings are meant to speed up matching a wrench to the bolt in front of you.
- 3-piece all steel wrench set
- 6, 8, and 10 inch sizes
- Full polish chrome finish
- Lifetime warranty
Who it's for
DIYers and home mechanics who want one wrench set that adjusts to different bolt sizes instead of stocking a full fixed wrench set. Less ideal for professionals who need repeated exact torque on the same bolt size all day.
Strengths and trade-offs
Drawn from this product's published specifications.
- Three sizes cover a wide range of bolt work
- Chrome finish resists corrosion
- Backed by a full lifetime warranty
- Adjustable jaws are less precise than fixed wrenches
- Only three sizes included, no smaller or larger options
Performance notes
Full polish chrome resists corrosion and the wide jaw opening is built to grip a range of bolt sizes without needing a separate wrench for each. The set meets ASME specifications, which sets a baseline for build quality across all three sizes.
