What should I pay attention to for half-thread self-tapping stainless steel screws?

For screws, the thread type of the screw is divided into machine thread and self-tapping thread. There are full thread and half thread in the self-tapping thread. So what should be paid attention to when ordering half-thread self-tapping stainless steel screws?

If the customer says that he wants to order half-thread self-tapping stainless steel screws, then he needs to know the length of the thread and the diameter of the rod (the part without threads under the head). Especially the diameter of the rod must be known because the size of this place will affect whether the screw needs to be opened.

When the diameter of the shaft of the half-thread self-tapping stainless steel screw is too small, the screw manufacturer must also consider whether the size of the head can meet the customer’s requirements and whether it can be expanded using this size of the wire. If the material does not expand, you need to consider changing to a larger size wire. The rod needs a cut to make the diameter of the rod meet the customer’s requirements. This increases cost.

Therefore, when customizing half-thread self-tapping stainless steel screws, special attention should be paid to the diameter of the rod, which is related to our cost.
