What is Fasteners?
🔩 Fasteners represents a complete system of precision titanium components engineered for Aerospace & Defense applications. Standard/custom threaded parts, small sizes, various head types (hex/socket/flat) The system integrates 0 distinct component types manufactured through 3 specialized processes.
Engineering & Design Principles
Material: Grade 9 (Ti-3Al-2.5V) is standard for aerospace fasteners. Lower strength than TC4 but better cold heading formability. Grade 5 for high-strength bolts.
Form: Wire/small bar is the standard form for fasteners. Direct cold/hot heading, material utilization >95%.
Standards & Material Specifications
Standards: AMS 4934 / ASTM B348 Gr9, solution+aged (STA), 100% thread inspection

1 Part Feature Analysis
Small cylindrical parts with external/internal threads, hexagonal/flange heads, shank and chamfer
- ⚠️ Thread galling
- ⚠️ Stress concentration at thread root
- ⚠️ Weight reduction
- ⚠️ Corrosion fatigue
- ⚠️ Preload relaxation
2 Material Selection Rationale
Grade 9 Ti-3Al-2.5V — Medium strength, good formability
Grade 9 (Ti-3Al-2.5V) has moderate strength with excellent cold-heading formability for fasteners. Beta-Ti (Ti-15V-3Cr-3Sn-3Al) for ultra-high strength applications.
3 Form Selection Rationale
Wire / Small Bar — for fasteners, springs, medical
Wire/small bar is the standard form for fasteners. Direct cold/hot heading, material utilization >95%.

Process Pitfalls:
- ⚠️ Ti fasteners require anti-galling coating (Al-bronze plating, MoS2 coating)
- ⚠️ Thread rolling gives 30% higher strength than cutting; rolling is mandatory
