Socket Head Cap Screws vs. Hex Head Bolts
I have an application that is resulting in failed 7/8" hex head bolts. I'm early in the investigation phase, but have read that a SHCS is stronger than the same size hex head bolt. One reason stated is simply because better alloys are used, which gives them higher minimum tensile strength. Others have said that the design makes them stronger, but no explanation behind that claim. Does anyone know if it is true that the design makes them inherently stronger? If so, can you explain why?
