Why does the hardened m2.5 flat head screw screwdriver slip?

Mr. Li needs to customize m2.5 flat head screw. In the telephone communication, we confirmed the size, material and surface treatment of the screw with Mr. Li. Then Mr. Li asked us to quote.

After calculating the price, we reported the price to Mr. Li through WeChat. After receiving the price, Mr. Li asked how long it would take us to deliver.

Mr. Li’s m2.5 flat head screw production process is like this: heading → floor processing → tooth decay → hardening heat treatment. Floor-to-surface processing is not machine processing, but labor is required. So it takes about 12-17 working days.

After receiving the screws, Mr. Li assembled and there was a problem during assembly. Then Mr. Li called Shi Shi Tong and asked why the m2.5 flat head screw had hardened and would make the screwdriver slip. Because we have tested the screws before shipping, there is no screwdriver slip. Therefore, we said to Mr. Li that the torque of the screw is too great, causing the screwdriver to screw the slip. It is recommended that Mr. Li reduce the torque when assembling, and there will be no screwdriver slipping.

Mr. Li said that he would try it soon. After a while, Mr. Li called to tell us that after reducing the torque, there was no screwdriver slipping.
