Roofing Tek self drilling hex head screws With EDPM Washers , Mechanical Plating AS3566 Class 3 Surface


1. Product Description


Hex Washer Head Self Drilling Screws (Zinc-Plated Steel) are designed for use in metal applications. Self-Drilling Screws, also known as Tek screws, eliminate the need for a pre-drilled hole.


Like self tapping screws, self drilling screws cut threads while being installed. A self drilling screw, however, has a notched point that acts as a drill point and therefore does not require a pre-drilled hole before installing.


The generic name for these screws are Self Drilling,he length of the drill point determines the material thickness which the screw can reliably penetrate.When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined.


Australian standard AS3566 drilling screw anti-corrosion technology is a world-class cash technology. The use of this technology can greatly improve the anti-corrosion and anti-rust ability of screws. Ordinary electroplating screw salt spray test is only about 50 hours, while the AS3566 CLASS 3 drill tail screw salt spray test more than 1000 hours.


Mechanical galvanized and traditional galvanized, hot dip zinc compared to have a unique advantage:
1. No hydrogen embrittlement, no annealing phenomenon. Can guarantee high strength steel, cemented carbide just, spring steel and other parts have mechanical and structural mechanical properties, the use of reliable.
2. Uniform coating. Coating thickness from 5-100um within the controllable, silver-gray, and according to user requirements for closed or passivation, coloring.
3. Strong anti-corrosion. According to the thickness of the coating and post-treatment type salt spray corrosion resistance test can reach 100-1500 hours.
4. Environmental non-toxic The whole process of cyanide-free, no ammonia, no chelating agents and other toxic and harmful substances, no heavy metals. The following are the same as the "
5. Choose a variety of coatings easy. At present, the company's products to zinc-based, according to user requirements plating single metal coating, multi-metal coating.
6. save costs. The price of mechanical plating is much cheaper than ordinary zinc-nickel alloy plating.

3. Application


  • For the fastening process in steel, they are used on steel frame construction or fastening other materials on steel.
  • For the fastening process in wood, they are used for applications in wood structures or industrial lightweight constructions, such as roof deck, flooring.
  • For the fastening process in aluminum, they are used for special industrial applications, construction and manufacturing of windows.

4. Advantages


1.The Special technology treatment of the surface makes the product anti-corrosion , antirust and durable.

2.Exact forging standard of knife edge and high hardness of surface make it easy to drill.

3.Using the advanced technology to control the core hardness, avoiding rupture effectivity,

4. Quick self drilling , drilling , tapping, locking the oncce, and combining with the strength.

5. Save contruction time, improve working efficency.

6. Technology, professional manufacturing , quality assurance.


Advantages of mechanical galvanizing


1.Reliability


In the automotive industry has been used for 25 years


2. safety


Industry standards are recognized by many industry standards, in line with the global technical standards of various industries: BS: 7371, ASTM B695, Ford S437, GM 3044, VW TL155 etc.


3 Uniformity


Mechanical coating thickness is very uniform, so in line with the minimum thickness of the customer requirements of zinc metal is relatively small.


4. Corrosion resistance


The mechanical coating as a cathode and anodic coating shows excellent protection performance. If the coating thickness is appropriate, it can exceed 1500 hours of neutral salt spray test.


5. Simple operation and control, most of the process can be automatically operated


6.Environmental protection process, no pollution to the environment


7.Mature craftsmanship


8.High product quality, excellent combination of strength and uniformity, up to 8 or more
