Lithium electric brushless electric wrench application of lithium electric brushless electric wrench application of lithium electric brushless electric wrench is mainly used in steel structure industry installation, installation of steel structure high strength bolt, high strength bolt is used to connect steel structure contact, usually with bolts. High strength bolts can be divided into the torsional shear type and large hexagonal type two kinds, gb torsional shear type high strength bolt for M, M, M, M, now has not the national standard of M, M two; Gb large hexagonal high-strength bolts for M, M, M, M, M, M, etc. Generally for high strength bolts fastening should be at the beginning of the first tight end tight again, and every step needs a strict torque requirements. Torsional shear type high strength bolt at the beginning of the tight can use electric impact wrench or set the torque wrench, and eventually the torsional shear wrench must be used; Large hexagonal high-strength bolt at the beginning of the tight and tight would set the torque wrench must be used. Therefore, various electric wrench is needed for all kinds of fastening. Lithium electric brushless electric wrench the use of the use of lithium electric brushless electric wrench is primarily bolt at the beginning, it's very easy to use and is aimed at bolt pull (power switch. Electric torsional shear wrench mainly end of torsional shear type high strength bolt, it is the use of bolt pulling power switch, until the torsional shear type high strength bolt wobbler interrupted. Electric constant torque wrench may end up as well as at the beginning of tight tight, its use is to adjust the torque first, tighten bolt again. Digital display electric torque wrench LCD display torque values directly, convenient operation and more intuitive. Angle to the electric wrench main also belong to a kind of constant torque wrench, its use is to adjust the rotation degree first, tighten bolt again. Lithium electric brushless electric wrench is a kind of special electric wrench fastening bolt steel Angle part, its use and electric principle of torsion shear wrench.
