Key Features
Overview
The Klein 65407MAGM Metric Magnetic Color-Coded Nut Driver is a heavy-duty hollow-shaft nut driver designed for driving 7 mm hex nuts and fasteners, including nuts on threaded rod that run longer than the driver itself.
The shaft is hollow for its full length and the handle is pass-through, so the threaded rod simply slides through the driver instead of stopping against it. That makes it a practical choice for hanger rod, all-thread and long bolts where a standard nut driver bottoms out. The 6-point hex socket grips more of the fastener than a 12-point design, which helps on tight or worn hardware.
Size identification is quick: a color-coded dome stamp marks the 7 mm size. The shaft is 5.1 in. (130 mm) long and the driver measures 10-3/4 in. (274 mm) overall. The shaft is cold-forged alloy steel with a wrench-assist hex, and the rare-earth magnet sits behind a brass inner sleeve and strike plate for durability.
This driver is not insulated and will not protect against electrical shock. It suits electricians, HVAC installers and general contractors who run metric hardware and threaded rod.
Drive Nuts Down Any Length of Rod

No more stopping when the rod hits the end of the driver. The hollow shaft and pass-through handle clear the rod completely.
- Full-length hollow shaft
- Pass-through handle design
- 6-point 7 mm hex socket
A Magnet That Holds Up

The magnet pulls the fastener to the tip and stays protected inside the shaft, so it keeps working after hard use.
- Rare-earth magnet
- Brass inner sleeve and strike plate
