Specifications
The specifications of titanium small screws are not standardized and primarily depend on the specific manufacturer, product model, and application scenario (such as industrial, medical, or vacuum equipment). These screws typically feature lightweight, non-magnetic, and corrosion-resistant properties, making them widely used in aerospace, precision electronics, medical implants, and semiconductor equipment
Material
Base Material
Titanium pure material Gr2 ,Grade 5 (Ti-6Al-4V). This is the most common grade for high-strength applications.
Grade 2 (Commercially Pure Titanium)
Good corrosion resistance
Lower strength
Used in chemical equipment, consumer products
Grade 5 (Ti-6Al-4V)
Most common for screws
High strength, lightweight
Used in aerospace, bikes, medical implants
Alternative Materials
Other grades like Gr12(Commercially Pure) for less demanding applications or Grade 12 may be used where maximum corrosion resistance or formability is needed.
Standards & Compliance
Titanium screws often follow general fastener standards:
ISO 4762 (socket head cap screws)
ISO 7380 (button head)
DIN equivalents
ASTM standards (material-specific, e.g., ASTM F136 for medical)
Dimensions & Geometry
Specified using metric or imperial standards.
Metric (most common)
Diameter: M1, M1.2, M1.4, M1.6, M2, M2.5, M3, etc.
Length: e.g. M2 × 6 mm (2 mm diameter, 6 mm long)
Imperial (less common for tiny screws)
#000, #00, #0, #1, etc.
Thread Type
- Metric fine thread (for precision applications)
- Metric coarse thread (default for most small screws)
-
Thread pitch example:
M2 × 0.4 (0.4 mm pitch
Head Type
- Depends on how the screw is used:
- Pan head
- Flat (countersunk) head
- Button head
-
Socket cap (hex)
Torx head (common for precision devices)
Example Specification
A typical "small titanium screw" might be described as:
M2 × 6 mm, Grade 5 Ti-6Al-4V, Torx T6, ISO 7380 button head, anodized
Applications
Aerospace Structures (air frames, engines)
High-Performance Automotive and Racing
Marine and Shipbuilding Equipment
Chemical Processing Plants
Medical Implants and Surgical Instruments (using specific biocompatible grades)
High-end Bicycles and Sporting Goods
