CRAFTSMAN Mechanics Tool Set, SAE / Metric, 135-Piece (CMMT12024)

Product overview

Craftsman CMMT12024 Socket Set: What to Know

CMMT12024 is the only set in this comparison covering all three common drive sizes, 1/4 inch, 3/8 inch, and 1/2 inch, in a single case. That breadth is also why its piece count needs context: Craftsman's own website lists the product as '135-Piece' in the title and URL slug on one product page, but a specification table on that same domain lists 138 individual line items. This discrepancy could not be resolved from Craftsman's public materials, so both numbers are reported here rather than picking whichever sounds better. Either way, because the set spans three drive families, a large share of the count is genuinely distinct sockets and ratchets rather than case padding.

Craftsman's spec sheet lists 72-tooth ratchets (plural, at least one per drive size) with a 5-degree arc swing, a slightly wider swing than the 4-degree ratchets in the GearWrench and Tekton sets above, though still a reasonably fine spec. Craftsman's own copy describes the sockets as full-polish chrome finish; some of Craftsman's marketing text refers to 6-point sockets specifically, so buyers who need 12-point sockets for rounded or damaged fasteners should double-check the exact listing before assuming both point types are included.

The case is a durable blow-mold design with metal hinges, specifically built to fit into Craftsman's own metal storage boxes, a real ecosystem advantage if you already use Craftsman storage, though not a factor if you don't. Buyers should also note that a separate Amazon bundle listing exists pairing CMMT12024 with a 12-piece Craftsman screwdriver set (CMHT65044) under a different ASIN; the standalone 135-piece set verified here (ASIN B07ND1FVDP) does not include that screwdriver set.
