Stainless steel flat head self tapping screws

When it comes to stainless steel flat head self tapping screws, many people think of the type of thread that is self-tapping. Because this type of application is very extensive. In addition, what are the thread types of stainless steel countersunk head tapping screws?

stainless steel flat head self tapping screws Conical self-tapping end: Generally, when the thread is twisted, it is squeezed (called “tip”, a small amount of metal is removed) to form a sharp end, and the tip end of the tip is broken before the thread is formed to form a sharp end. It is suitable for thin steel sheets of 2.5mm or less; it has good neutrality and penetrability in use, and is used for connection and assembly performance of multi-layer boards.

stainless steel flat head self tapping screws Plane self-tapping end: The end of the blank is a truncated cone, which forms a tapered guide when the thread is milled. For the connection of thick steel plate and steel structural profiles, screwing into blind holes can effectively utilize the blind hole depth; it is also suitable for soft and hard plastic parts, non-ferrous metal parts, cast aluminum and steel castings.

Self-drilling end: The end is similar to the bit structure. When installing, the bottom hole is drilled from the end part, and then the thread is tapped. The whole process is completed in one go, and the efficiency is high. It is used in applications such as construction and automobile manufacturing for multi-layer panel connection and large panel (light construction) connection, and has good comprehensive economic benefits.
When selecting, it should be noted that the total thickness of the joint should be less than the length of the end of the screw bit structure to ensure that the drilling has been completed before tapping.

In addition to the above, stainless steel flat head self tapping screws are also self-tapping and cutting-edge, triangular teeth and other types, which are not listed here. Shenzhen Shishitong screw manufacturers serve batch customers, and can customize screws according to your requirements.
