Why are most of the watch screws slotted head

Screws are closely related to our lives, ranging from screws on aircraft equipment to small screws on communication electronic equipment watches. I don't know if you usually pay attention to it. Most of the watch screws are slotted. I believe you are also very curious. Follow the footsteps of the editor to show you.

Watch screws are precision screws. The reason why they are all slotted screws is determined by their processing methods. The precision screw of the watch is processed by CNC, and the slotted head is relatively simple to process naturally. If the cross recessed head is to be processed, the cost is high, and without secondary processing, the cross cannot be processed by turning. And the cross groove heading machine is easy to process, because the watch screw is small, so the cross groove is also very small, which may cause some difficulties in heading. Moreover, slotted screws can be made flat and thin, and Phillips screws cannot be made as thin as a slotted because of the depression in the middle and the convex surrounding.

Therefore, most of the watch screws are slotted, and a small number of requirements will use the phillips slot head. In fact, whether it is a slotted screw or a cross-slotted screw, our Shenzhen Heat Hardware Co,ltd custom screw manufacturer can tailor it to your requirements.
