Overview

The CRAFTSMAN CMCF930B is a 14.6 inch wrench weighing 2.3 pounds, with a listed capacity of 0.38 inches that lines up with a standard 3/8 inch drive. It suits users who need extra leverage on stubborn fasteners in a garage or shop toolbox.

At just over 14 inches, this wrench sits between a compact ratchet and a full size breaker bar, giving more leverage than a stubby tool without the bulk of a longer bar. Craftsman does not list a material or finish in the available specs, so buyers relying on a specific alloy or warranty claim should confirm those details before purchase.

Who it's for

Fits DIYers and home mechanics who already use 3/8 inch drive sockets and want added reach for tight or rusted bolts. Less useful for anyone needing a compact tool for cramped engine bays.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out

Drive size lines up with common 3/8 inch sockets
Compact enough for a standard toolbox

What to check first

No material or torque spec listed

Performance notes

The 14.6 inch length is the main functional detail available, and it is what gives this wrench its leverage advantage over shorter ratchets on tight or corroded fasteners. No torque rating or ratcheting mechanism is specified, so output beyond length and drive size cannot be confirmed from the listing.
