Shi Shi Tong helps customers solve the problem of 85mm long socket screws

Miss Pan from Shenzhen found the Shi Shi Tong screw manufacturer on the Internet. Miss Pan said that she would order a 85mm long socket screws. Miss Pan asked Shi Shi Tong whether this screw does not break. Miss Pan’s previous screw made by other screw manufacturers was not broken, or the head was broken, so Miss Pan had little headache.

Considering that Miss Pan’s 85mm long socket screws are made of carbon steel, the required strength rating is 8.8. I thought that if the hydrogen was not completely removed before, the screw was hydrogen embrittled, causing the 85mm long hexagonal screw to break. Or the strength of the screw does not meet the requirements of Miss Pan, causing the screw to break during use and so on.

Miss Pan said that she would send a sample of the courier to show us what the problem is, and avoid these problems when it is time to produce. After receiving a sample from Miss Pan, Shi Shi Tong tested it and found that the grade of the screw did not reach 8.8 and there was hydrogen embrittlement. And the slot of the screw is too deep, and it will break when screwing.

After responding to these questions with Miss Pan, I gave some advice to Miss Pan. According to the recommendations of Shi Shi Tong, Miss Pan’s factory redesigned the drawings of the 85mm long socket screws, and the effect after the change was much better.
