Description

📌 Bolt Friction Coefficient Tester: Fully Automatic LS-500B Overview

Bolt Friction Coefficient Tester is a critical instrument for evaluating the torque-tension relationship of high-strength bolts used in steel structure projects. The Fully Automatic Bolt Friction Coefficient Tester (LS-500B), developed by our factory, supports M16 to M30 bolts and fully complies with GB50205-2020 “Steel Structure Engineering Quality Control Regulation.” This system accurately measures tightening torque and axial force to calculate the friction coefficient, ensuring connection reliability and construction safety.

Equipped with a smart display and automatic control system, it supports real-time monitoring, automatic resetting, and instant report printing—greatly improving operational efficiency. With high-precision torque and force sensors, and zero manual intervention, the LS-500B Bolt Friction Coefficient Tester delivers consistent and accurate results for quality inspection and industrial testing applications.

The system’s core advantages include rapid execution, automatic data logging, and built-in friction coefficient calculation. It eliminates human error and improves consistency in bolt connection assessments. Advanced sensors enable reliable evaluation of axial force and torque ratio.

Whether for verifying bolt connection reliability, ensuring compliance with engineering standards, or supporting on-site inspections, the Bolt Friction Coefficient Tester provides indispensable testing capabilities for steel construction and manufacturing industries.
