結構連接用螺栓性能等級分3.6、4.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9等10余個等級，其中8.8級及以上螺栓材質為低碳合金鋼或中碳鋼并經熱處理(淬火、回火)，通稱為高強度螺栓，其余通稱為普通螺栓。那么，m27高強螺栓用多大的梅花頭扳手?

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?

電動扭剪扳手幫助您裝、拆螺拴、螺母，同時能比較準確地控制擰緊扭矩。利用螺栓定扭矩，當扳手達到一定扭矩時即可剪斷螺栓的梅花頭部分，其扭矩精度和軸向拉力是靠螺栓的定扭矩V型切口來確定的。拆裝扭力矩大、比手工更保險可靠。廣泛用于鋼結構橋梁、廠房、發電設備等設施的施工作業。

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.

電動扭剪扳手體積小、重量輕、狹小空間操作自如。

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

Electric torsion wrench S-30LP working:

電動扭剪扳手S-30LP主要是終緊扭剪型高強螺栓的，它的目的就是把扭剪型高強螺栓的梅花頭打斷即可。工作時將扳手頭對準螺栓頭，扣動開關即可開始工作，幾秒后，螺栓梅花頭將被扭斷，然后抽出扳手扣動扳機將梅花頭彈出，即結束工作。

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.
