DIN7985 Machine Screw Stainless Steel

Self tapping pin Screws are also used for thin metal plate connection. The thread is a common thread with arc triangle section and the surface of the thread has a high hardness. Therefore, when connecting, the screw can also tap out the internal thread in the bottom hole of the thread of the connected part to form a connection. The screw has the characteristics of low screw in torque and high locking performance, and has better performance than the ordinary tapping screw, and can be used instead of Machine Screw.

18-8 stainless steel provides good corrosion resistance and strengt

Steel is often used in applications where strength is the primary consideration

The difference between self drilling tapping screw and common tapping screw is that when connecting, the common tapping screw must go through two processes: drilling (drilling the bottom hole of thread) and tapping (including fastening connection); while the self drilling tapping screw is connected, the two procedures of drilling and tapping shall be combined once. It first uses the drill bit in front of the screw to drill holes, then screw the screw to tap (including fastening connection), saving construction time and improving the construction efficiency.

Also if you need Hex Bolt,Hex Nut,Anchor or others ,we can provide too.
