Tester for the torque coefficient and preload of high-strength bolt assemblies in steel structures, with automatic test procedure.
Overview
This testing machine is specially designed for detecting the torque coefficient of high-strength bolts used in steel structures. Except for bolt installation and removal which require manual operation, all other test procedures are automatically completed. The product complies with Q/320211JCD01-2005 *Technical Specification for Automatic High-Strength Bolt Tester*, GB/T 1228-2006, GB/T 1229-2006, GB/T 1230-2006, GB/T 1231-2006, GB/T 3633-1995 and other relevant standards for high-strength bolt assemblies used in steel structures.

FAQ
Q1: What standards does the High-Strength Bolt Torque Coefficient Tester comply with?
A1: The High-Strength Bolt Torque Coefficient Tester is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the High-Strength Bolt Torque Coefficient Tester be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
