How long does the pan head stainless steel screws deliver?
David of the United States sent us an inquiry via email saying that he wanted to customize a socket head shoulder screws and asked if we could customize it. In the email, David wrote the thread diameter, length, step size, and head size of the hex socket screw. The thread is not our usual right thread, but the left thread, and the tail of the thread should have a 1mm dog point or lead in for easy installation. The corner is convenient for him to assemble and the tolerances of the screws are required. David said that when he started in the early stage, he only needed 600 pcs, and then waited for the test to pass the batch order.
