Pan Head Torx Drive Self Drilling Bimetal Tek Screws
Torx Drive Bimetal Self-Drilling Screws with CE& SGS certificate, Pan Head Tek Screws, Premium Anti-Corrosive Fasteners for Stainless Steel
Core Features:
Torx Drive (6-Lobe) Advantage
- Maximized Torque: The star-shaped drive allows for much higher torque without "cam-out" (the bit slipping out of the head).
- Extended Tool Life: Reduces wear and tear on driver bits.
- Better Centering: Ensures stable driving during high-speed installation.
Bi-Metal "Ultimate" Performance
- Corrosion-Free: The stainless steel body (A2/A4) ensures the screw won't rust even in coastal or industrial pollution.
- Fast Drilling: The friction-welded carbon steel point can penetrate thick steel plates (up to 12.5mm for heavy-duty series).
Head Style Options:
- Pan Head: Ideal for surface mounting where a neat, rounded look is desired.
Special Lubrication Coating :
- Often treated with a specialized dry-film lubricant to reduce friction during the tapping process.
