316 stainless steel A4-50 Phillips pan head screw DIN7985 is a corrosion-resistant fastening component designed for applications requiring reliable mechanical performance and excellent environmental resistance. The 316 stainless steel A4-50 Phillips pan head screw DIN7985 is manufactured from A4-50 stainless steel, equivalent to 316 stainless steel characteristics, providing improved resistance to chloride corrosion, moisture, and harsh industrial environments.
The 316 stainless steel A4-50 Phillips pan head screw DIN7985 features a pan head design and Phillips drive, offering convenient installation and stable fastening performance. It is widely used in marine equipment, chemical processing systems, food machinery, outdoor structures, and industrial assemblies where corrosion-resistant stainless steel fasteners are required.
Product Overview
The 316 stainless steel A4-50 Phillips pan head screw DIN7985 is a machine screw manufactured according to DIN7985 dimensional requirements. It is designed for applications requiring a flat seating surface, reliable clamping force, and easy installation with standard Phillips tools.
A4-50 stainless steel provides excellent corrosion resistance compared with A2 stainless steel, especially in environments exposed to salt water, chemicals, and industrial contaminants. The 316 stainless steel A4-50 Phillips pan head screw DIN7985 is suitable for applications where long service life and stable fastening performance are important.
The pan head design provides a larger bearing surface, helping distribute tightening pressure and reducing damage to connected components. This makes it suitable for precision equipment, panels, housings, and general industrial assemblies.
