Is There Any Requirement For The Across Flat Of High Tensile Socket Head Cap Screws?

Many industries use a lot of screw fasteners every day, such as construction, machinery, electronics and so on. Do high tensile socket head cap screws have any requirements for across flat? What is the across flat of the hexagon socket?

This statement is not correct. If there is no requirement for the across flat of high tensile socket head cap screws, there will be several cases. One is that the opposite side exceeds the diameter of the head and cannot be produced. One is that the opposite side does not exceed the diameter of the head, but the opposite side is also very large, close to the edge of the head, which will also cause fracture of the head edge during production. One is that the opposite side is too small, will lead to deep enough groove, in the use of a lot of time to spend tightening, not worth it.

Generally speaking, the opposite side of high tensile socket head cap screws is basically the same as the diameter of the thread. When considering the hexagonal socket opposite side, not only should we consider whether it can be used or not, but also whether it can be used for sliding batch and so on.
