结构连接用螺栓性能等级分3.6、4.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9等10余个等级，其中8.8级及以上螺栓材质为低碳合金钢或中碳钢并经热处理(淬火、回火)，通称为高强度螺栓，其余通称为普通螺栓。那么，m27高强螺栓用多大的梅花头扳手?

The performance grades of bolts used for structural connections are divided into more than 10 grades, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. Among them, bolts with grades 8.8 and above are made of low-carbon alloy steel or medium carbon steel and heat treated (quenched and tempered), commonly referred to as high-strength bolts, while others are commonly referred to as ordinary bolts. So, what is the size of the ring wrench used for the M27 high-strength bolt?

电动扭剪扳手帮助您装、拆螺拴、螺母，同时能比较准确地控制拧紧扭矩。利用螺栓定扭矩，当扳手达到一定扭矩时即可剪断螺栓的梅花头部分，其扭矩精度和轴向拉力是靠螺栓的定扭矩V型切口来确定的。拆装扭力矩大、比手工更保险可靠。广泛用于钢结构桥梁、厂房、发电设备等设施的施工作业。

Electric torque wrench helps you install and remove bolts and nuts, while accurately controlling tightening torque. By using bolts to set torque, when the wrench reaches a certain torque, the plum blossom part of the bolt can be cut off. The torque accuracy and axial tension are determined by the V-shaped notch of the bolt at the set torque. Dismantling has a high torque and is safer and more reliable than manual work. Widely used for construction operations of steel structure bridges, factories, power generation equipment, and other facilities.

电动扭剪扳手体积小、重量轻、狭小空间操作自如。

The electric torsion wrench has a small volume, light weight, and can be operated freely in narrow spaces.

Electric torsion wrench S-30LP working:

电动扭剪扳手S-30LP主要是终紧扭剪型高强螺栓的，它的目的就是把扭剪型高强螺栓的梅花头打断即可。工作时将扳手头对准螺栓头，扣动开关即可开始工作，几秒后，螺栓梅花头将被扭断，然后抽出扳手扣动扳机将梅花头弹出，即结束工作。

The electric torsion shear wrench S-30LP is mainly used for final tightening of torsion shear high-strength bolts, and its purpose is to break the plum blossom head of the torsion shear high-strength bolt. When working, align the wrench head with the bolt head, press the switch to start working. After a few seconds, the bolt ring head will be twisted and broken. Then, pull out the wrench and pull the trigger to eject the ring head, which ends the work.
