　　扭剪型和高強度螺栓大六角頭型的區別

The difference between torsion shear type and high-strength bolt large hexagonal head type

　　一、外觀不同

1、 Different appearance

　　1、高強度螺栓大六角頭：大六角頭螺栓的螺帽是正六角形的。

1. High strength bolt with large hexagonal head: The nut of the large hexagonal head bolt is a regular hexagon.

　　2、扭剪型螺栓：頂端部有梅花卡頭。

2. Twisted shear bolt: There is a plum blossom clamp at the top.

　　二、施工方式不同

2、 Different construction methods

　　1、高強度螺栓大六角頭：使用定扭矩扳手施工，由于其施擰時并不握裹螺桿，在旋轉螺母的同時可能會帶動螺桿進行“同轉”，無謂消耗扭矩值，造成無法擰緊。故將螺桿頭設計成大六角，在發生同轉的情況時，可以用普通扳手予以臨時固定，避免同轉現象。

1. High strength bolt with large hexagonal head: When using a fixed torque wrench for construction, as it does not grip the screw during tightening, it may drive the screw to rotate simultaneously while rotating the nut, unnecessarily consuming torque value and causing inability to tighten. Therefore, the screw head is designed as a large hexagon, and in case of simultaneous rotation, an ordinary wrench can be used to temporarily fix it to avoid simultaneous rotation.

　　2、扭剪型螺栓：使用扭剪型扳手施工，其根部使用正反向扭桿直接通過“梅花頭”夾緊螺桿本身，故施擰時不會發生同轉現象。

2. Twisted shear type bolt: Construction is carried out using a twisted shear type wrench, and the root of the bolt is directly clamped by a "plum blossom head" with a forward and reverse torsion rod, so there will be no simultaneous rotation during tightening.

　　三、強度等級不同

3、 Different strength levels

　　1、高強度螺栓大六角頭：屬于普通螺絲的高強度級。

1. High strength bolt with large hexagonal head: belongs to the high-strength grade of ordinary screws.

　　2、扭剪型螺栓：是大六角高強螺栓的改進型，為了更好施工高強螺栓的施工必須先初緊后終緊，初緊高強螺栓需用沖擊型電動扳手或扭矩可調電動扳手。

2. Twist shear type bolt: It is an improved version of the large hexagonal high-strength bolt. In order to better construct high-strength bolts, the initial tightening must be followed by final tightening. The initial tightening of high-strength bolts requires the use of an impact type electric wrench or a torque adjustable electric wrench.
