What are the causes of stainless steel hexagon bolt rusting? How to avoid it? 1. The surface of stainless steel hexagon bolt adheres organic juice (such as melon and vegetable, noodle soup, phlegm, etc.) and forms organic acid under the condition of water and oxygen. The corrosion of organic acid on metal surface will rust [...]
There are many parts of machinery and equipment that use inner hexagon bolts to fix parts. However, because they are often disassembled, the inner hexagon of the bolts is easy to grind round, and it is difficult to remove them with the hexagon wrench. This paper introduces two methods of hexagonal nut hexagon bolt parts, [...]
Introduction to High strength external hexagon combination screw for buildings and workshops: High strength external hexagon combination bolt for steel structure is mainly used in railway and highway bridge, boiler steel structure, industrial workshop, high-rise civil building, tower and mast structure, hoisting machinery and steel structure where friction type high-strength bolt combination screw is required. [...]
What problems should be paid attention to when high strength steel structure bolts replace high strength bolts? 1) When the hole position is not correct, forced alignment will damage the thread of high strength bolt, resulting in the change of torque coefficient and pre tension. 2) It is possible that the internal stress in the [...]
