Talking about: the characteristics of composite stainless steel self-drilling screws

product structure:

304/316+410 composite stainless steel self-drilling screw series

304/316+ alloy steel after heat treatment, composite stainless steel self-drilling screw series

Product Features:

For highly polluting environments and coastal areas; high temperature; humid environment; coupled with automobiles; factories emit a large amount of sulfide-containing exhaust gas and particles, which are the causes of metal oxidation and corrosion.

Composite stainless steel self-drilling screw is a completely corrosion-resistant stainless steel self-drilling screw; the screw locking part and head are made of (18-8) austenitic system stainless steel material; the tapping part and the tip end drilling part are made of alloy The surface of steel (or 410 stainless steel material) has been specially treated; super research and development; anti-rust and corrosion-resistant life can achieve very good results.

Because the thread drilling and tapping area are all specially hardened metal; when the iron plate is tapped; the stainless steel part is introduced into the thread; the previous stainless steel tapping screw is completely eliminated; it is often locked due to thread wear The phenomenon; to achieve a complete conclusion; and to maintain the highest coefficient of pull-out strength. (Guide: Cold heading and processing of threaded fasteners)

Pre-drilling is not required; it can replace the existing stainless steel tapping screws, which is most suitable for the installation of various wall materials; construction; thereby improving the anti-rust ability.

Composite stainless steel self-drilling screw; because of its unique design of the self-drilling die; used in steel structure engineering; can achieve the lightest load; the fastest cutting effect; not only can reduce the user’s workload; at high altitudes Homework; or a difficult working environment to stand on; it can exert its outstanding effect even more.

Scope of application:

Because of its strong rust resistance; corrosion resistance life can reach full effect; its acid resistance; alkali resistance; weather resistance for coastal areas and highly polluted climates; suitable for products and buildings with various corrosion resistance requirements.
