Electric shear wrench for snugging and final tightening of torshear (twist-off) high-strength bolts in steel structures.
Overview
This hand-held AC electric wrench is designed for snugging and final tightening of torshear (twist-off) high-strength bolt assemblies in steel structures. The spline socket engages the spline end of the bolt; the wrench applies torque automatically and final tightening is completed when the spline pintail shears off at the prescribed torque, giving small torque scatter and consistent quality. The gear train is made of heat-treated special alloy steel with no reaction torque. A D-shaped main grip plus an auxiliary handle make it easy to operate; interchangeable sockets cover M16M30 bolts. It is a standard power tool for bridges, industrial buildings and high-rise steel construction sites.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Electric Shear Wrench for Torshear Bolts comply with?
A1: The Electric Shear Wrench for Torshear Bolts 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 Electric Shear Wrench for Torshear Bolts 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.
