Features spaced thread segments that reduce friction during drilling while maintaining strong grip and load distribution. This design prevents material splitting in brittle substrates (e.g., plastic, thin metal) and ensures secure anchoring with enhanced resistance to loosening under vibration or stress.
The textured knurling on the screw head enhances grip and torque control during installation, while the self-tapping threads cut precise grooves into materials for a secure, vibration-resistant hold. Ideal for applications requiring manual tightening or limited tool access.
Winged Self-Tapping Thread Design:
Winged Self-Tapping Thread Design:
The screw features raised “wings” or flanges along the threads, increasing surface contact and grip strength. This design enhances stability, resists pull-out forces, and prevents loosening in soft or brittle materials like plastic or composite substrates. Ideal for lightweight assemblies requiring extra anchorage.
Anti-Corrosion Coating on Threads:
Anti-Corrosion Coating on Self-Tapping Threads:
A rust-resistant coating (e.g., zinc, galvanized) applied to self-tapping screws prevents oxidation and extends lifespan in humid, outdoor, or chemically exposed environments. It maintains thread integrity, ensures smooth installation, and reduces maintenance needs for long-term reliability.
