generally speaking, bolts are used to connect two objects, usually through light holes, which need to be used together with nuts, and a single bolt does not work. Tools are usually spanners. The head is mostly hexagonal, which is generally larger than the vertical right angle observed by theodolite with a minimum reading of less than 2. Carriage bolts are used in the groove. The square neck is stuck in the groove during the installation process, which can prevent the bolt from rotating. Carriage bolts can also be used by colleagues and classmates. Our machine moves parallel in the groove.
