Pan head tapping screws and flat head screws are our common screw fasteners. Although they are used for the fastening of products, the use of pan head tapping screws and flat head screws is very different. It is also why screw fasteners are divided into so many head shapes, grooves and threads. Today, Shishitong screw manufacturers will simply say: What is the difference between a pan head tapping screw and a flat head screw: the thread is a self-tapping tooth, and the tail is a pointed screw fastener, which is mainly used for non-metal or The soft metal does not require a preset hole. It can be directly rotated into the product by using the pan head self-tapping screw. It can be used as a connection fastening without the use of a nut.
The flat head screw, the head is flat, the thickness of the head is thin and thick, and it is a flat screw fastener. It can have mechanical teeth that work with the nut and can be designed as a self-tapping tip screw.
The biggest difference between the pan head self-tapping screws and the flat head screws is the difference in the head type, which also determines the different use scenarios between the two. The flat head screws are mostly used in sophisticated electronic products such as mobile phones, computers, watches and other fine products. These products have small internal structure space, and the screw fasteners that need to be used also need to be very fine. The head of the flat head screw can save a lot of space, and more threads are reserved for the screw part for connecting and fastening products. Pan head screws are mostly used in home appliances, furniture and other products that do not have strict requirements on the appearance of the products.
