## Description

Product 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.             Safety Warning          Always wear approved eye protection.NOT insulated. Will NOT protect against electrical shock.

## Features

- Hollow shaft allows for nut driving on unlimited bolt length
- Color coding for easy identification of different sizes
- Wrench assist for additional torque
- Magnetic feature helps retain nut
- Heavy duty shaft with classic Cushion-Grip handle
