StressTel leads the market in ultrasonic bolting extensometers with the BoltMike III. The StressTel BoltMike III Ultrasonic Bolt Extensometer measures strain in critical bolts per ASTM E1685-00 providing necessary data on clamp load and induced stress in tensioned fasten.

Based on customer input, the BoltMike III includes many features not found in competitive systems. Features such as large, easy-to-read display; preloaded bolt grade material constants for rapid calibration and setup; and automatic temperature compensation for fast, repeatable, and accurate fastener tension measurements.

StressTel's StressWare data collection and analysis software is included with each BoltMike III to interface data to your PC and provide quick and easy report generation.

Ultrasonic strain measurement is the accepted method of verifying bolt preloads in critical joints and the StressTel BoltMike III is the preferred tool for the application.
