根据设计原理，所有的机械三通和机械四通在上下两片之间有一定的间隙，所以，在拧紧螺栓和螺母时不要试图将上下两片紧靠在一起（金属对金属）。扭矩过大将导致安装失败。参考以下表格中螺栓的扭矩力。
The mechanical tee and cross is designed with a gap between the bolt pads.Please do not attempt to bring the bolt pads together (metal-to-metal)when tightening the bolts and nut.Excessive torque may cause joint failure.The following table gives you some recommended bolt fastening torque.
