Product Description

Our CSK screws are high-quality carbon steel fasteners with grade 8.8 strength, featuring flat head hexagon design for optimal performance in self-tapping applications.

Key Features:
  • Manufactured from carburized steel for superior strength
  • Heat-treated for optimal mechanical properties
  • High surface hardness with tough core ("soft outside steel")
  • Surface protection treatment (typically plating or phosphating)
  • Produced using high-speed cold heading process for consistent quality
Types of Self-Tapping Screws
  • Ordinary self-tapping screws: Wide thread design, mostly plated surface
  • Self-cutting tapping screws: Available in pan head, countersunk head, raised countersunk head, and hexagonal head variations
  • Self-extruding tapping screws: Typically machine thread with triangular cross-section
  • Self-drilling tapping screws: Eliminate need for pre-drilling holes
  • Wallboard tapping screws: Special 60° thread angle with phosphate treatment
  • Combination self-tapping screws: Integrated with washers for enhanced performance
Grade 4.8 vs Grade 8.8 Bolts

For applications requiring standard strength with budget considerations, Grade 4.8 bolts are suitable. For critical connections needing high strength and reliability, Grade 8.8 bolts are recommended. Always consider specific engineering requirements when selecting bolt grades.

Blackening Treatment Benefits
  • Enhanced rust prevention through stable iron tetraoxide film
  • Improved surface durability with reduced flaking
  • Better sliding properties when combined with rust preventive oils
  • Maintains aesthetic appeal while providing functional benefits
