Specifications
titanium six star head self-tapping screw is a titanium self-tapping fastener with a Torx drive (commonly called a "six-star" head). It combines the corrosion resistance and lightweight properties of titanium with the high torque transfer of a Torx recess.
Material
Common Titanium Grades
| Grade | Characteristics | Typical Use |
|---|---|---|
| Grade 2 | Commercially pure titanium, excellent corrosion resistance | Chemical & marine |
| Grade 5 (Ti-6Al-4V) | High strength, aerospace grade | Aerospace, racing |
| Grade 7 | Enhanced corrosion resistance | Chemical processing |
Main Features
1. Titanium Material Advantages
Titanium screws offer:
Excellent corrosion resistance
Suitable for marine, chemical, and outdoor environments.
High strength-to-weight ratio
Stronger than many stainless steels while much lighter.
Non-magnetic properties
Useful in medical, aerospace, and electronic applications.
High temperature resistance
Performs well in elevated-temperature environments.
Biocompatibility
Widely used in medical and biomedical equipment.
Six-Star (Torx) Head Benefits
Compared with Phillips or slotted heads, the Torx drive provides:
Higher torque transmission
Reduced cam-out (driver slipping)
Better assembly efficiency
Less wear on tools and screw heads
Improved automation compatibility
Self-Tapping Function
A self-tapping screw can:
Cut or form threads directly into material
Eliminate pre-threaded holes
Reduce installation time
Improve fastening efficiency
It is commonly used in:
Thin metal sheets
Aluminum profiles
Plastic components
Composite materials
Lightweight structures
Common Applications
Aerospace
Used in aircraft interior panels, lightweight structures, and corrosion-resistant assemblies.
Marine Industry
Ideal for seawater environments because titanium resists saltwater corrosion extremely well.
Medical Devices
Used in surgical instruments and implant-related equipment.
Electronics
Applied where non-magnetic fasteners are required.
Automotive & Motorcycle Upgrades
Popular in racing and high-performance vehicles for weight reduction.

Application
Aerospace: Used in high-performance environments where weight, strength, and resistance to corrosion are critical
Medical: Common in surgical implants and devices due to their biocompatibility and resistance to body fluids.
Marine: Ideal for use in environments exposed to seawater, such as boat hulls, marine structures, and underwater equipment.
Chemical and Food Processing: Titanium's non-reactive nature makes it perfect for equipment in contact with chemicals, food, or pharmaceuticals.
Automotive: Used in lightweight, high-strength applications within vehicles, especially for fasteners that must withstand extreme conditions.
