Material and Manufacturing Process
The SS Phillips Pan Head Screws with Collar are primarily manufactured from high-grade stainless steel materials like SS304 and SS316. SS304 offers excellent strength and resistance to oxidation, while SS316 carries superior corrosion resistance, especially in chloride environments—making it ideal for marine and chemical applications.
The production process involves:
- Raw Material Selection and Inspection
- Cold Forging or Machining of Pan Head & Collar
- Thread Rolling Under Controlled Compression
- Heat Treatment (if required)
- Surface Treatment (Passivation or Electropolishing)
- Final Quality Check and Packaging
The integration of a precise forging process with thread rolling ensures high dimensional stability and reliable thread engagement.
Typical Applications and Industries
SS Phillips Pan Head Screws with Collar are utilized across diverse industries including:
- Consumer Electronics Assembly (for casings and internal fixtures)
- Marine Equipment and Shipbuilding (high corrosion resistance)
- HVAC Systems
- Aerospace and Automotive Components
- Industrial Machinery Assembly
- Furniture Hardware Manufacturing
- Electrical & Communication Cabinets
In particular, their collar design is beneficial in load-bearing applications and where vibration resistance is required.
