Shandong 丨high - strength bolt torque wrench
Aug 21, 2020
High-strength bolts are high-strength bolts and belong to a kind of standard parts. In general, high strength bolts can bear a larger load than ordinary bolts of the same specification.
According to the construction process is divided into: twisted shear high-strength bolts and large hexagonal high-strength bolts.
The big hexagon high strength bolts belong to the high strength class of ordinary screws, while the torsional shear type high strength bolts are the improved type of the big hexagon high strength bolts for better construction.
In the construction of high-strength bolts, first the initial twist and then the final twist must be made. The initial twist of high-strength bolts shall be made by impact electric wrench or torque adjustable electric wrench. There are strict requirements for the final twisting of high-strength bolts. The final twisting and shearing type high-strength bolts must use the twisting and shearing type electric spanner, and the final twisting torque type high-strength bolts must use the torque type electric spanner.
The large hexagon strong bolt consists of a bolt, a nut and two washers. The twisted shear type high strength bolt consists of a bolt, a nut and a washer.
High-strength bolt torque wrench:
1. Electric torque wrench
The electric torque wrench is specially designed for fastening large hexagon bolts with torque requirements. When working, the torque value shall be set in advance. When the wrench reaches the set torque value, the wrench will stop automatically.
brand electric torque wrench models, a full range.

2. Electric shear wrench
Electric shear wrench to tighten torsional shear type high strength bolt, and after completion of the fastening will cut the wobbler kept inside the sleeve sticktite, then pull the trigger to wobbler pop-up, power to 220 v or 110 v ac power, compared with the traditional hexagon bolts, torsion shear bolts with electric electric shear wrench, construction is convenient and quick, accurate torque control and convenient to check.
