Before You Buy

When selecting from these Craftsman twenty-piece sets, pay attention to the specific items included in the total piece count. In the socket-based kits (CMMT12108, CMMT12008, and CMMT12114), the twenty-piece total encompasses the ratchet handle, sockets, and drive accessories or extensions. However, the product listings do not specify the complete, line-by-line socket size range. Furthermore, none of these socket kits include specialty components like spark plug sockets, swivel joints, or drive size adapters, which must be acquired separately if needed.

Tool storage and mounting options also differ across the range. While the CMMT12108, CMHT68133, and CMMT12114 specifically include modular cases compatible with the Craftsman VERSASTACK system, they do not include mounting brackets for tool carts or non-compatible storage boxes. The CRAFTSMAN Ratchet Wrenches (CMMT87220) comes with an integrated case, but the older twenty-piece wrench set does not specify a case. Checking your storage drawer capacity or modular stack layout prior to purchasing ensures your new tools fit smoothly into your shop.

FAQ

What is the difference between a 72-tooth and a 90-tooth Craftsman ratchet?

A 72-tooth ratchet mechanism requires a 5-degree arc swing to advance a fastener, while a 90-tooth ratchet operates with a tighter 4-degree swing (or 5 degrees in low-profile designs). The 90-tooth design enables technicians to turn fasteners in confined engine bays where handle clearance is limited.

Which Craftsman ratchet set to buy for general automotive repairs?

The CRAFTSMAN 20-Piece Standard (model CMMT12114) is the most balanced option for general automotive work. Its 3/8-inch drive handles the torque required for brakes, engine brackets, and suspension parts, while its 90-tooth low-profile head maneuvers easily within crowded modern engine compartments.

Are the sockets in these Craftsman 20-piece sets 6-point or 12-point?

The socket-based mechanics sets, including the CMMT12008 and CMMT12114, use 6-point sockets. Six-point sockets contact the flat sides of hex bolts to minimize fastener rounding under load. In contrast, the ratcheting combination wrenches feature 12-point box ends to provide faster tool positioning in tight spaces.

What does VERSASTACK compatibility mean on Craftsman tool cases?

VERSASTACK compatibility indicates that the molded case features external interlocking latches designed to lock onto Craftsman VERSASTACK toolboxes, organizers, and rolling towers. This system allows technicians to stack and secure multiple tool sets together for stable transport between job sites.

How do the reinforced open ends on Craftsman ratcheting wrenches function?

The reinforced open end is built to break loose stuck, seized, or overtightened fasteners that require substantial breaking torque. Once the fastener is loosened, mechanics can flip to the 12-point ratcheting box end to spin the fastener off quickly without removing the tool.
