Key Features
Overview
The Klein Knurled Hex Bit Socket Set, Metric, 13-Piece (model 65213HEXM) is a metric hex bit socket set designed for driving hex-head fasteners with 1/4-inch, 3/8-inch and 1/2-inch drive ratchets and drivers.
The set covers metric hex sizes from 2 mm to 14 mm: 2, 2.5, 3, 4, 4.5, 5, 6, 7, 8, 9, 10, 12 and 14 mm. Each socket is made from chrome-vanadium steel with a chrome and black phosphate finish, and the size is bold-stamped on every socket so you can find the right one at a glance.
Klein splits the sizes across three drive sizes on purpose. The 1/4-inch drive handles precision work, the 3/8-inch drive is the all-rounder, and the 1/2-inch drive is there when you need torque. The knurled base makes it easier to spin a fastener in by hand before you put a ratchet on it.
Everything lives in a MODbox case that measures 3.45 in. (88 mm) by 1.63 in. (41 mm) by 7 in. (178 mm) and weighs 1.41 lb. This is a good fit for mechanics, equipment techs and anyone who works on metric hardware.
Start Fasteners With Better Grip

The knurled base gives your fingers something to hold, so you can thread a fastener in by hand before the ratchet takes over.
