CRAFTSMAN CMMT87010 7-Piece SAE Flex Reversible 72-Tooth Ratchet Wrench Set

The CMMT87010 covers SAE only: 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, and 3/4 in across 7 ratcheting combination wrenches. All six critical SAE automotive sizes are present; the set stops short of 1/4-in at the small end and anything above 3/4-in. Steel is listed as Alloy Steel without further alloy designation, finished in Full Polish Chrome. Box ends are 12-point ratcheting with a 72-tooth mechanism and a 180-degree flex head on a pin joint, letting the head pivot to approach fasteners at an angle. Owners rate it well, with no jaw-spread, fastener-rounding, or chrome failure complaints reported, though the review base is still modest. No storage pouch or case is included.

The right pick for a home mechanic who services primarily domestic vehicles (US-built trucks, older American cars) and wants a compact SAE ratcheting combination wrench set for bolt-on maintenance work in tight spaces · the flex head and 72-tooth mechanism provide real access advantages over standard fixed-head wrenches. Skip it for any vehicle with metric fasteners (virtually all modern imports and most new domestic models); the set has no metric coverage. Also skip it if your work requires sizes outside 5/16-3/4-in, or if you need a 6-point box end for recovering corroded or already-rounded hex heads · the 12-point geometry, while standard, applies torque at the fastener corners rather than the flat faces and elevates rounding risk on damaged fasteners.

No chemical exposure pathway · the CMMT87010 is an Alloy Steel hand tool with no SDS. The steel body is recyclable through standard ferrous scrap streams. No storage pouch is included, removing the typical nylon-pouch end-of-life concern that affects most wrench set environmental scores. CRAFTSMAN combination wrenches are designed for decades of service; the Lifetime Limited Warranty, honored through Lowe's and Ace Hardware, supports the long-haul tool-lifecycle story. Eye and hand protection during mechanical work reflects the task environment, not any chemistry in the tool itself.
