Why do carbon steel inner hexagon screws slip?

Have you ever had a circumstance with the screws slipping or turning round? Do you know why they skid? Today, we will take an example of 12.9-grade carbon steel inner hexagon screws to illustrate it!

Mr. Fu from Guangzhou called Shi Shi Tong this afternoon and asked why the sample of his customized 12.9 carbon steel inner hexagon screws slipped. He didn’t know the reasons. Manager Song used video dialogue to let colleagues in the quality inspection department operate the screws testing process again, and even screwed it with a screwdriver, but the screw was still intact. So, Mr. Fu guesses that the cause of too much strength. Manager Song told Mr. Fu that when the torque used exceeds the design and production can withstand the force, it will cause the carbon steel inner hexagon screws to slip. In view of this situation, Manager Song suggested Mr. Fu do a torque test first, to prevent over artificial torque from making the screws slip.

After dealing with this matter, Manager Song also told us incidentally that in production, the inner hexagonal groove is not deep enough or the wrench used has wear, which will also lead to slipping. Shi Shi Tong is a screw processing factory that pursues precision manufacturing and produces screws in accordance with customers’ demands. It must ensure the quality of products.
