Is there tiny drawings to customize the long pan head screws?

Jim’s company has developed a new product. Due to the design problem, a new screw is needed to tighten the product better. According to their idea, the screw’s head is a pan head, maybe 210mm long also called the long pan head screws. But the idea isn’t designed yet. Maybe you want to customize it?

For the screw manufacturer, if the customer has drawings sometimes, it will save them a lot of communication costs, and they can understand the customer’s requirements more quickly, so as to communicate more smoothly. Second, even if there are no drawings, the screw makers want the customer to have samples, because maybe they want to make drawings through tiny samples of the long pan head screws to confirm whether they want the shape or tiny tolerances.

If the customer no drawings or samples, so the customer can describe the need to screw manufacturer long pan head screws size and functions to achieve, and then the screw manufacturer would have to make the drawings according to the customer’s description, after the customer confirm the drawing is ok, if ok, then will be very smooth in the communication, showed that the two people are in the same communication channel. However, if the customer cannot describe clearly the size, material, etc. of the product they need, they will not be able to customize.
