·Degreasing (Anti-rust single packing)	: Part Number SL-□□
·Precision cleaning (Degassing double packing)	: Part Number SH-□□
·Electrolytic polishing + precision cleaning (Degassing double packing)	: Part Number SHD-□□

Product Part Number	Cleaning Method	Packaging Type	Effects Compared to Uncleaned Product	Environment (Standard)	Process
SL-□□	Degreasing	Anti-rust packing	Oil removal	General environment	Regular assembly process
					Post battery assembly process
SH-□□	Precision cleaning	Degassing double packing	Oil removal Dust removal	Clean environment (Class 10 to 1,000)	Battery assembly process
					LCD-related post assembly process
					In-vehicle camera assembly process
SHD-□□	Electrolytic polishing + precision cleaning	Degassing double packing	Oil removal Dust removal Outgas reduction	Vacuum environment Clean environment (Class 10 to 1,000)	Pre-semiconductor process
					Liquid crystal deposition process
					Pre-OLED process

■Notes

They are designed to sit flush with or below the surface of the material they are fastening, providing a clean and smooth finish. These screws are commonly used in applications where a protruding screw head is undesirable, such as in door hinges and countersunk holes.
Question: What are the key features of Flat Head Machine Screws?: Answer: - Low-Profile Design: Sits flush with the surface for a streamlined appearance.
- Versatile Application: Suitable for woodworking, metalworking, and other industrial applications.
- User-Friendly: The Phillips head provides excellent tool engagement, reducing the risk of slippage and stripped screws.
- Variety of Materials: Available in materials such as stainless steel, brass, and titanium, offering corrosion resistance and durability.
Question: How do I choose the correct Flat Head Machine Screw for my project?: Answer: When selecting Flat Head Machine Screws, consider the following factors:
- Thread Size: Ensure the screw thread matches the tapped hole or nut.
- Length: Choose a length that provides sufficient engagement without protruding excessively.
- Material: Select a material that suits the environmental conditions, such as stainless steel for corrosion resistance.
- Drive Type: Phillips, slotted, or other drive types based on tool compatibility.
- Surface Treatment: Opt for treatments like zinc plating or black oxide for additional protection and aesthetic purposes.
