Stainless Steel Phillips CSK Head Tapping Screws
Product Overview
Phillips CSK Head Tapping Screws are self-tapping fasteners designed for use in sheet metal, plastic, or wood materials. Featuring a countersunk (CSK) flat head and Phillips drive, these screws provide a flush surface finish after installation, ensuring aesthetics and safety. Made from high-grade stainless steel, these tapping screws offer excellent corrosion resistance, strength, and reliability, making them suitable for a variety of industrial and commercial applications. Their threading is engineered to form or cut threads into pre-drilled holes, eliminating the need for pre-threaded holes and streamlining assembly processes.

Material and Manufacturing Process
These screws are primarily manufactured from Stainless Steel grades SS304 and SS316, which are widely known for their corrosion resistance properties and durability in both indoor and outdoor conditions. The production process includes:
- Cold heading to shape the screw head
- Thread rolling for uniform and sharp threads
- Heat treatment for enhanced mechanical properties
- Surface passivation or polishing for increased corrosion resistance and finish quality
- 100% quality inspection for consistent performance
Thanks to this refined process, Phillips CSK Head Tapping Screws offer tight tolerances and superior fastening strength.
