鋼結構用高強度扭剪型螺栓連接副屬于鋼結構摩擦型高強度螺栓連接使用的連接件，為高強度螺栓的一種，主要應用于鋼結構件的連接和固定。鋼結構螺栓一般等級為10.9級，也有8.8級，但較少采用，成套裝配。鋼結構用高強度螺栓分為二款，分別是大六角頭螺栓和扭剪型螺栓。扭剪型螺栓的標準為GB/T3632，每套包括一個高強度扭剪型螺栓GB/T3632、一個鋼結構用高強度螺母GB/T1229和一個鋼結構用高強度墊圈GB/T1230，并應分屬同批制造。
The high-strength torsional shear bolt connection pair for steel structure belongs to the connector used for friction type high-strength bolt connection of steel structure. It is a kind of high-strength bolt, which is mainly used for the connection and fixation of steel structures. The general grade of steel structure bolts is 10.9 and 8.8, but they are rarely used and assembled in complete sets. High strength bolts for steel structures are divided into two types: large hexagon head bolts and torsion shear bolts. The standard of torsion shear bolts is GB / t3632. Each set includes a high-strength torsion shear bolt GB / t3632, a high-strength nut GB / t1229 for steel structure and a high-strength washer GB / t1230 for steel structure, which shall be manufactured in the same batch.

Features of high strength torsional shear bolts for steel structures:
1.螺栓的成型加工由頭部、尾端、螺紋及凹槽部之成型均在同一工廠內以冷間鍛造成型，其加工精度，品質之穩定性，均相當優良。
1. The forming and processing of bolts consists of the forming of head, tail end, thread and groove in the same factory by cold forging. Its processing accuracy and quality stability are quite excellent.
2.熱處理使用連續式鋼帶熱處理爐。其標準的溫度及碳濃度自動記錄，能有效控制淬火溫度及氣體濃度，以防止滲碳或脫碳，確保螺栓達到要求之機械性能。
2. Continuous steel strip heat treatment furnace shall be used for heat treatment. The standard automatic recording of temperature and carbon concentration can effectively control the quenching temperature and gas concentration to prevent carburization or decarburization and ensure that the bolts meet the required mechanical properties.
3.有效利用管制圖及制程能力分析方法，徹底實施制程管制，以追蹤加工及品質狀況，提供完整資料供工程設計者參考。
3. Effectively use the control chart and process capability analysis method to thoroughly implement process control, so as to track the processing and quality status and provide complete data for the reference of engineering designers.
4.考慮到扭剪型螺栓的使用特殊性，為防止扭剪型螺栓在安裝過程中滑動打轉，在設計加工過程中我們增加扭剪型螺栓頭部下方的防滑處理，有效避免了因螺栓打滑引起安裝不當導致的及質量事故。
4. Considering the particularity of the use of torsional shear bolts, in order to prevent the torsional shear bolts from sliding and rotating during installation, we added anti-skid treatment under the head of torsional shear bolts in the process of design and processing, which effectively avoided safety and quality accidents caused by improper installation caused by bolt sliding.
