Description
The STH Series Locking Force Tester is developed specifically for evaluating the effective torque and locking force of steel hexagon nuts in accordance with GB/T3098.9 standards. It is suitable for testing ordinary and high-strength hexagon nuts across a defined fastener size range. The STH-300K model combines a dynamic torque sensor and a clamping force sensor, enabling both parameters to be measured simultaneously in a single test cycle. This integrated approach improves testing consistency while reducing overall inspection time.
The system features an improved mechanical structure and high-power drive technology to ensure stable, repeatable, and accurate results. With computer-connected software, users can observe real-time dynamic curves of torque and clamping force, making data analysis easier and more detailed. The dual-screen display presents torque and force values clearly, supporting practical operation in laboratory and industrial quality control environments.
