The cap head machine screws is approved by Joel, Germany.

Joel sent us an enquiry last month, saying that I want cap head machine screws. And gave us the drawings. And asked us a few questions:

One is whether the cap head machine screws or the screw should be opened; how long will it be delivered; can it be tested for 500 hours in salt spray; if you want this cup, it is not so easy to fall out. After that, we answered the questions according to Joel and gave the corresponding solutions.

After confirming that all the problems can be solved, Joel immediately placed an order for us and said that our products were of good quality in the first delivery, and they met their requirements after testing. In this month, the order for the cap head machine screws is added.
