Description

Fastening nuts on threaded rod can be a struggle due to the confined space and obstructions around the rod. Lateral movement is limited. On long sections of threaded rod, traditional nut drivers bottom out so you can only get the nut so far up the rod. Klein's Heavy-Duty Nut Driver features a through-handle, completely hollow shaft to allow for nut driving on unlimited bolt lengths. Wrench assist provides greater torque while the magnetic tips will grab any nut appropriately.

  • Why so shallow on the depth
Size: 1/4-Inch Tip, 4 Inch Shaft
The hole that the items go into is barely big enough for a nut. Could have been a few mm deeper. So far it worked ok though. I am going to be using it as a driver for all the bits that are widely varied. This could be not meant for that. Couldn't figure out what to call the tool that is meant for that if not a driver? ... show more

  • Perfect
Size: 7/16-Inch Tip, 4 Inch Shaft
I needed to calibrate the height of lamps held by threaded rods, and this tool is great, 100% recommended, just one detail the magnet to hold nuts came off, in the end I fixed it with quick glue.

  • Built well
Size: 9/16-Inch Tip, 4 Inch Shaft
This tool has been a main stay in my bag for years now. I work with a lot of 3/8 hardware to ground equipment in my profession. It actually got a upgrade recently and includes flat edges almost like a hex head so you could also use a wrench to break bolts or nuts loose.
