What are the bolt placement and bolt spacing requirements?

The bolt arrangement can be divided into parallel and staggered arrangements. The parallel bolt arrangement is simple, neat and compact, and the size of the connecting plate used is small, but the cross-section of the component is greatly weakened; the staggered bolt arrangement is not compact, the size of the connecting plate used is large, and the cross-section of the component is weakened. Less stress.
