High Strength Bolt Torque Wrench

High-strength bolts are increasingly used. Two strength grades of 8.8 and 10.9 are commonly used, of which 10.9 is the majority. The strength grade of ordinary bolts is lower, generally 4.4, 4.8, 5.6.

High-strength bolts are mainly used in steel structure engineering. A very important feature of high-strength bolts is that they are limited to one-time use, generally used for permanent connections, and repeated use is strictly prohibited.

The construction of high-strength bolts must be screwed first and then finally. The initial screwing of high-strength bolts requires an impact-type electric wrench or torque-adjustable electric wrench; and there are strict requirements for final screwing of high-strength bolts. Torsional shears must be used for final screwing of high-strength bolts. Type electric wrench, torque type electric wrench must be used for final torque type high-strength bolts.

Hanpu torque wrench mainly includes torsion shear type electric wrench and torque type electric wrench

The torsional shear type electric wrench is mainly used to tighten the torsion shear type high-strength bolts, and after the fastening is completed, the sheared torx head is kept inside the sleeve without falling, and then the trigger is pulled to eject the torx head.

HANPU TOOL

Torque type electric wrench is mainly used for fastening hexagonal bolts with torque requirements. The power is 220v or 110v AC power supply, with torque controller, and the output torque can be adjusted within a certain range.
