What size of shear wrench should be used for M30 high strength bolts?

The performance grades of bolts for steel structure connection are divided into more than 10 grades such as 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, and 12.9. Among them, the bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel and are heat-treated (quenched, tempered). They are generally called high-strength bolts, and the rest are generally called ordinary bolts. So, What size of shear wrench should be used for M30 high strength bolts?

The electric shear wrench helps you install and remove bolts and nuts, and at the same time can control the tightening torque more accurately. Use the bolt to determine the torque. When the wrench reaches a certain torque, the spline of the bolt can be cut off. The torque accuracy and axial pulling force are guaranteed by the torque V-shaped notch of the bolt. The disassembly and assembly torque is large, which is more safe and reliable than manual. Widely used in the construction of steel structure bridges, workshops, power generation equipment and other facilities.

Shandong Machinery Industrial Co., Ltd. specializes in the production of electric shear wrenches, electric torque wrenches and other products, factory direct sales, quality assurance. The produced electric shear wrench is small in size, light in weight, and free to operate in a small space. The electric shear wrench S-30LP produced by Shandong is suitable for the tightening of M30 high-strength bolts.

  Parameters ：

The electric shear wrench S-30LP is mainly for tightening torsion shear type high strength bolts. Its purpose is to break the spline of the torsion shear type high strength bolts. When working, align the wrench head with the bolt head and pull the switch to start working. After a few seconds, the bolt spline will be twisted off, and then pull out the wrench and pull the trigger to eject the spline, which ends the work.

Features of Electric Shear Wrench S-30LP :

Lighter weight.

Better performance.

Can achieve more reliable fastening.

The construction is simple and efficient, without considering the reaction force.

Shandong Machinery Industrial Co., Ltd. has many departments such as R&D, production, sales, and after-sales service. Relying on a strong technology development system and market-oriented, it constantly develops new power tools. The products have been widely used in construction, machinery, Bridges, railways, electric power, water conservancy, metallurgy, chemical industry, iron and steel, and other large domestic and foreign enterprises and engineering construction, having won unanimous praise from domestic and foreign users.
