Different truss head self tapping screws

There was no problem during the process of use. Therefore, when Miss Yang’s company wanted truss head self tapping screws, Miss Yang once again found the Shi Shi Tong screw manufacturer.

Miss Yang sent the drawings of the truss head self tapping screws to the Shi Shi Tong screw manufacturer. Ms. Yang said that this screw allows us to provide samples to her first. Miss Yang’s company needs to try the assembly first to see if their design is ok. Then mass production.

When I looked at Miss Yang’s drawings, I found that the slot of the truss head self tapping screws is different from the common slot. The common slot is cut directly or hit the edge of the head, but this slot is wrapped inside the head, not to the edge.

According to Miss Yang’s drawings, we quickly offered a quote to Miss Yang. Then Miss Yang directly asked us to make a contract for her, and then let the financial payment.
