1. Product Introduction:

1. The LLG-24HY anti-slip coefficient testing instrument is mainly suitable for testing the anti-slip coefficient of friction surfaces in high-strength bolt connections of grade 10.9 and 8.8, as well as for testing the anti-slip coefficient of friction surfaces in torsional shear type high-strength bolt connections (a special wrench for torsional shear needs to be ordered separately), testing, and research.

2. High-strength bolt connection: A general term for high-strength bolts and their matching nuts and washers;

3. Anti-slip coefficient: The ratio of the external force that causes the friction surface of the connection to slide to the sum of the pre-tension of the high-strength bolt perpendicular to the friction surface in high-strength bolt connections;

4. LLG-TEST LCD microcomputer force measuring instrument, with four physical channels and a total of 24 logical channels in 6 groups.

5. Parameter backup and recovery function, peak hold function, automatic calibration function.

6. Specifications for high-strength large hexagon head bolts: M16, M20, M22, M24, M27, M30.

7. Specifications for torsional shear type high-strength bolts: M16, M20, M22, M24.

8. To facilitate users in connecting to a computer, the LLG358 interface is set up (needs to be ordered separately), allowing data to be transmitted to a computer for further processing and printing of test reports.

9. This device is easy to operate, convenient to carry if sent for calibration by measurement departments, and extremely convenient for future equipment upgrades and maintenance. This device is currently a low-investment, high-return high-strength bolt testing instrument widely popular among high-strength bolt manufacturing enterprises, engineering quality testing institutions, steel structure construction units, engineering supervision agencies, high-speed railways, bridge electricity, and research institutions such as colleges and universities in China.
