Key Features
Overview
The Klein Tools Hollow Magnetic Color-Coded Power Nut Drivers, Metric, 6-Piece (32940M) is a six-piece set of hollow-shaft metric nut drivers for drills and impact drivers. This is a power nut driver set designed for driving nuts and hex screws on threaded rod, long bolts and recessed fasteners in electrical, mechanical and assembly work.
Sizes: 7 mm, 8 mm, 10 mm, 12 mm, 13 mm and 14 mm, each a 6-point hex on a 1/4" hex drive. The color coding makes it fast to find the right size in a pouch or drawer.
The hollow core is the main reason to choose these over standard power nut setters. With a 3-3/4" hollow depth, the driver can run a nut down threaded rod or a long bolt without the rod bottoming out in the socket. Each driver is 6" long for reach into recessed areas.
Retention comes from powerful rare-earth magnets that increase in size with each hex size, so fasteners are held securely for one-handed driving. The drivers are made of high-grade impact steel, impact-rated for the most demanding driving tasks, with a black oxide finish for corrosion protection.
No case is included. The set weighs 1.0 lb (454 g).
Who should buy it: electricians and mechanical contractors running nuts on all-thread for strut and hangers, equipment installers and assemblers working with metric hardware, and anyone tired of the standard nut setter bottoming out on long bolts.

The hollow shaft lets threaded rod pass inside the driver instead of stopping the nut short.
