Proper tightening of high-strength bolts is necessary to ensure the accuracy of high-strength bolt testing
Date：2018-09-21ID: 159Heat:
The high-strength bolt detector is mainly used for detecting the connection pairs of high-strength bolts. High strength bolts are mainly used in steel structure engineering to connect the connection points of steel plates. High strength bolts are divided into torsional shear bolts and large hexagonal bolts. Large hexagonal bolts belong to the high-strength machine of ordinary screws, but torsional shear high-strength bolts are an improved type of large hexagonal high-strength bolts. In order to facilitate construction, high-strength bolts must be loosened before final tightening. The initial tightening of high-strength bolts requires an electric wrench or a torque adjustable electric wrench, while the final tightening of high-strength bolts has strict requirements. The final tightening of torque type high-strength bolts must use a torque type electric wrench, and the final tightening of torsional shear type high-strength bolts must use a torque type electric wrench. It is necessary to use a twist shear type electric wrench. Jinan Liling Testing Machine Co., Ltd. has strong technical research and development capabilities. It independently develops high-strength bolt detectors, torque wrenches, and shear wrenches, providing cost-effective and highly practical high-strength bolt detectors and application wrenches for steel structures and testing units!
