Product Description
4.2mm A193 B8 A453 GR660 Flange Pan Head Self Drilling Screw DIN7504
Product Specifications
| Attribute | Value |
|---|---|
| Name | Metal Screw |
| Standard | DIN, ASME, ANSI, ISO |
| Material | Stainless steel |
Product Description
The tail of the screw is designed with a drilling tail shape, offering exceptional hardness and superior performance compared to ordinary screws. These self-drilling screws provide excellent connection strength and can be directly used to drill and lock objects without auxiliary processing, significantly improving work efficiency.
Applications
| Automotive | High-strength applications including automotive engines, heavy-duty machinery, and bridge construction, preferred for their larger support area and superior anti-loosening performance. |
| Mechanical | Used in mechanical, electronic, automotive, and construction fields to connect various mechanical parts, circuit boards, engines, transmissions, and building structures. |
| Energy | For connecting power generation equipment and transmission lines in the energy industry. |
| Architectural | Used in construction engineering, shipbuilding, and petrochemical industries to connect building structures, improve ship navigation safety and stability, and ensure petrochemical equipment safety. |
Material Specifications
| Aluminum | Excellent thermal and electrical conductivity but naturally soft. May produce gelatinous buildup during processing. |
| Titanium | Well-suited for EDM machining due to alloy viscosity. Requires deionized water as a medium to control heat. |
| Steel | Very strong metal often machined with wire cutting machines for complex features. Generates significant heat during processing. |
| Brass | High tensile strength and easy to machine, but requires slow cutting speed due to softness. |
Feature Advantages
Stainless steel screws feature excellent corrosion resistance through surface treatment methods that isolate the metal from corrosive environments. Key benefits include:
- Corrosion resistance, wear resistance, and high hardness
- 316 and 316L variants contain 2-3% molybdenum for enhanced corrosion resistance, especially in chloride environments like saltwater
- Surface treatments provide durable protection against corrosion
