Common screw types and common screw materials

Common types of screws

A. Machine Screw
B. Tapping Screw (divided into two kinds of metal and plastic)

Sheet Metal Tapping Screw
Plastic Tapping Screw

C. Wooden Screw
D. Drywall Screw
E. Self Drilling Screws (stainless steel drilling screws, composite drilling screws)

Structure and scope of application of Self Drilling Screws:

1. SUS304/316+ alloy steel composite stainless steel drilling screws after heat treatment of high carbon steel.

2. Features: The composite stainless steel drilling screws are completely corrosion-resistant stainless steel drilling screws, and the locking part and head of the screws are austenitic stainless steel materials; The tapping part and the end of the drill tail are divided by alloy steel (or high carbon steel material), the surface is specially treated, ultra-extreme research and development; Corrosion-resistant life for ultimate results.

3. The screw drill tail and tapping area are specially hardened metal, when entering the iron plate, the stainless steel part can be smoothly introduced into the metal, which can completely exclude the previous stainless steel tapping screws, which are often locked due to thread wear and deformation, to achieve complete conclusion; And maintain the highest coefficient of drawing strength.

4. Because of its unique drilling design, it is most suitable for a variety of wall material installation, construction, and in steel structure engineering, it can achieve the fastest cutting effect with the lightest tapping speed.

5. For coastal areas and high pollution, high temperature, humidity, ocean, carbonated environment, and automobiles, factories emit a large number of sulfur-containing waste gas and particles, which are the causes of metal oxidation and corrosion, due to its excellent performance, corrosion resistance life can reach the full effect.

Scope of use:

Due to strong anti-rust ability; Corrosion-resistant life can reach full effect; It is acid-resistant; Alkali resistant; Weather resistance for coastal areas and highly polluted climates; Suitable for all kinds of corrosion resistant products and buildings.

Head shape
Various head shapes of screws: cylindrical head, semi-countersunk head, countersunk head, spherical cylindrical head, pan head, semi-round head, hexagonal head...

Common screw material

A. Low Carbon Steel: carbon steel, carbon steel is divided into low carbon steel, medium carbon steel, high carbon steel and alloy steel

B. SS-304: Stainless Steel. 304, 316 are stainless steel

C. SS-302: Stainless Steel 302: Good structural toughness

D. Aluminum 5052

E. Brass

F. Bronze

G. UNS C11000 Copper

There are many commonly used screw materials, roughly two kinds, one is carbon steel, that is, iron, carbon steel can be divided into low carbon steel, medium carbon steel, high carbon steel. The other is stainless steel, stainless steel has stainless steel SUS201.304.316 and so on.
