SmartBolts are specialty fasteners with a built-in visual indicator that shows the tension developed as the bolt is installed.
The SmartBolt tension indicating bolts continuously measure and displays tension information. From loose to tight and back again, the system is reliable and repeatable through countless cycles of operation. The indicator gradually darkens from bright red to black as the fastener is sufficiently tensioned.
SmartBolts are compatible with a wide range of fastener types, and can be adapted to fasteners of nearly every possible tension specification, grade, finish, and coating. They are ideal as excavator bolts or slew bearing bolts.
