Carbon Steel Grade 12.9 Yellow Zinc Plated Galvanized GAL Trumpet Head Drywall Screws DIN18182
1,Description:
The tail of the screw is generally shown as the shape of drilling tail, the hardness of this screw is very strong, compared with ordinary screws, not only the ability to maintain better, the effect of connecting the object is very firm, for this performance of the screw, generally do not need auxiliary processing, you can directly drill a hole on the object directly to lock the object, not only very convenient to use, It can also greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of staff in various fields.
| Applications | |||||
| car | In high-strength applications such as automotive engines, heavy-duty machinery, and bridge construction, they are preferred for their larger support area and better anti-loosening performance. | ||||
| mechanical | Mechanical, electronic, automotive, construction and other fields, used to connect various mechanical parts, circuit boards, engines, transmissions, building structures, etc | ||||
| energy | For the energy industry, brackets and fixtures used to connect power generation equipment and transmission lines | ||||
| architectural | In the field of construction engineering, shipbuilding, and petrochemical industry, it is used to connect building structures, improve the navigation safety and stability of ships, and ensure the safety and stability of petrochemical equipment | ||||
The accuracy of the screws is usually 6g (Class 2, the US specification "IFI" is 2A teeth), and the rough screws used in construction projects are 8g (Class 3, "IFI" is 1A teeth).The main purpose is to make industrial products composed of a fixed body, in the use of teeth and teeth often can not be close, too hard to lock the screw head is broken, or poor dental lock is not tight and failed to meet the conditions of use, are precision problems. Screws are "quantity products", not hand-made artworks, in mass production, in order to achieve high precision and stable quality and popular price supply to consumers for the purpose.
3,Specifications:
| material | |||||
| aluminium | Aluminum has excellent thermal and electrical conductivity. However, aluminum is naturally soft and may produce gelatinous buildup after processing. If not properly operated, it is difficult to cut during processing. | ||||
| titanium | Edm machining is well suited for titanium because the process can withstand the viscosity of this alloy and break down lengthy chips. However, deionized water is needed as a medium to help control the heat generated during processing. | ||||
| steel | Steel is a very strong metal, and many manufacturers tend to use wire cutting machines instead of CNC machines for machining complex steel features. However, this material generates a lot of heat, so necessary precautions need to be taken. | ||||
| brass | Brass has a high tensile strength and is easy to cut by machine. But the cutting speed should be slow because it is a soft metal. | ||||
4,Feature Advantage:
Abroad, in general construction, great emphasis is placed on choosing the right fastener products. Single-line coarse-threaded dry-wall screws, as an alternative to double-line fine-threaded dry-wall screws, are more suitable for use in the connection of wooden keels. In the domestic market, double-line fine-thread dry-wall screws have been used exclusively for a long time. It takes some time to change the usage habits
The thread of single-line coarse-threaded drywall screws is wider, and the corresponding tapping speed is also faster. At the same time, since the structure of the wood material itself will not be damaged after being driven into the wood, they are more suitable for the installation of wooden keels than double-line fine-threaded drywall screws.
### **Advantages of Stainless Steel 316 and 316L**:
1. **Excellent corrosion resistance**: Both 316 and 316L contain 2-3% molybdenum, which gives them stronger corrosion resistance compared to the 304 series, especially in chloride environments like saltwater, making them suitable for high-corrosion settings.
2. **Good high-temperature performance**: Stainless steel 316 offers better strength and oxidation resistance at high temperatures compared to the 304 series, making it suitable for high-temperature environments.
3. **Low carbon content (316L)**: 316L is the low-carbon version of 316, with a carbon content of less than 0.03%, reducing the risk of intergranular corrosion after welding. This makes 316L ideal for food and pharmaceutical equipment that requires extensive welding.
4. **Easy to clean**: The surface of 316 and 316L stainless steel is smooth and easy to clean, effectively preventing food residues, dirt, and microorganisms from adhering, meeting food safety standards.
5. **Non-magnetic**: In their annealed state, both are non-magnetic, which is beneficial for products requiring low magnetic properties.
Excellent corrosion resistance**: Both 316 and 316L contain 2-3% molybdenum, which gives them stronger corrosion resistance compared to the 304 series, especially in chloride environments like saltwater, making them suitable for high-corrosion settings.
Food-grade stainless steel 316 and 316L are austenitic stainless steels that are widely used in industries like food processing and pharmaceuticals, where high hygiene and corrosion resistance are critical. The primary difference between the two is their carbon content. Below are their advantages and applications:
#### **1. Food processing equipment**:
- **Food transportation pipelines**: 316 stainless steel is used in pipelines that transport liquids and food, particularly in acidic or high-salt food production environments.
- **Meat and dairy processing equipment**: These materials provide excellent corrosion protection for equipment that handles salt, acids, and other corrosive substances in meat and dairy production.
- **Storage tanks and containers**: 316 and 316L are widely used in fermentation tanks, mixing tanks, and storage containers in the food and beverage industry, especially when dealing with acidic or salty foods.
#### **2. Pharmaceutical industry equipment**:
- **Pipelines and transfer systems**: In pharmaceutical manufacturing, 316L is ideal for piping that transfers drug solutions and pharmaceutical-grade water, preventing corrosion during welding.
- **Pharmaceutical production containers**: Due to their corrosion resistance, easy cleaning, and low contamination risk, 316 and 316L are commonly used for reactors and storage tanks in the pharmaceutical industry.
