Warning system identifies loose lug nuts

A new patent-pending indicator warning system from ZamLok System identifies loose lug nuts on commercial vehicles

A new patent-pending indicator warning system from ZamLok System identifies loose lug nuts on commercial vehicles. The ZamLok lug nut retention and torque monitoring system is available in standard 33 mm on 3.5 in. stud centers.

The system uses resistance between two nuts to minimize their ability to loosen up to 40 lbs.-ft. If they do loosen, than a warning indicator alerts the driver or shop personnel, explained Zamlok.

According to the company, the system saves time and money that is wasted due to unnecessary re-torqueing of lug nuts and also reduces the need for lug-nut road calls.
