Key Features
Overview
The Klein Metric Color-Coded Nut Driver, Heavy-Duty Hollow-Shaft, 7mm (model 65407M) is a metric nut driver designed for driving 7 mm hex nuts onto threaded rod without bottoming out.
The full hollow shaft is 5.1 in. (130 mm) long and the pass-through handle means rod length is not a limit. The 6-point hex design reduces the risk of stripping, and the shaft and handle are reinforced for heavy-duty use.
The Cushion-Grip handle is cellulose acetate, 1.25 in. (32 mm) in diameter. Overall length is 10.78 in. (274 mm) and the driver weighs 5 oz (142 g). It is alloy steel, is not insulated, and does not protect against electrical shock.
It suits electricians, HVAC installers and anyone who sets metric nuts on all-thread.
Nuts on Long Rod, No Bottoming Out

The hollow shaft lets the rod pass through the driver.
- Full hollow depth
- Cold-forged wrench-assist hex
