What is the quality of Shi Shi Tong's hex socket head cap screw?

Mr. Cheng previously purchased a hex socket head cap screw in Zhejiang, 8.8 grade nickel plated, the screws bought look very beautiful, and the price is very cheap. However, there was a problem when using it. I don't know what happened. The screw he bought was easily broken.

Mr. Cheng wondered why the screws that others bought were not easy to break, and there would be no problems. Later, when Mr. Cheng tested the hex socket head cap screw, he found that the torque did not reach 8.8. Mr. Cheng gave this question back to his supplier. The supplier re-offered the goods to Mr. Cheng. There is still a problem. Finally, Mr. Cheng did not find any more.

Occasionally, Mr. Cheng contacted Shi Shi Tong and first ordered samples from Shi Shi Tong to go back to the test. A week later, Mr. Cheng said that our hex socket head cap screw test was passed, and this time it will be officially purchased at Shi Shi Tong. How about the quality of Shi Shi Tong screws, Mr. Cheng will know.
