Manufacturing Capabilities for High-Precision Custom Fasteners
From cold heading to CNC machining and Threading, our integrated production capabilities support precision fastener manufacturing for automotive and heavy industrial applications.
With in-house forming, machining, heat treatment coordination, and inspection processes, we help engineers accelerate project cycles by turning designs into stable, production-ready fasteners.
Integrated Manufacturing Capabilities
Custom fasteners often involve complex requirements such as tight tolerances, material control, and performance under vibration.
Our manufacturing capabilities are structured to support these requirements through controlled forming, machining, and threading processes.
Each production stage is aligned to ensure consistency, repeatability, and stable performance in demanding applications.

Cold Forging
AYA Fasteners applies precision cold forging technology to produce high-strength fasteners with stable dimensions and excellent consistency. Forming at ambient temperature allows tight tolerances, improved mechanical properties, and reliable performance for demanding applications.
- High tensile strength and fatigue resistance
- Suitable for complex shapes
- Stable preload and repeatable dimensions
- Consistent, high-volume production with minimal cycle times
- Full in-house quality inspection and traceability
CNC Machining
AYA provides precision CNC machining services for custom fasteners and machined components used in automotive and industrial applications. Our machining capability ensures dimensional accuracy, stable tolerances, and reliable performance for functional parts.
- Cost-effective with minimal waste
- Tolerance up to ±0.001 mm
- Suitable for complex and non-standard geometries
- Smooth surface, less finishing
- Wide material machining capability
- Stable performance for assembly-critical components
Threading
Our threading processes deliver high-precision threads with consistent geometry and load-bearing performance. Both rolled and cut threading options are available to meet different strength and dimensional requirements.
- Thread rolling for improved fatigue strength
- Smooth thread surface finish
- High concentricity and repeatability
- Suitable for small- to medium-batch production
Surface treating
Our products meet the most rigorous industry standards. Should your fastener need to operate in extreme conditions and require special hardness, durability, or environmental resistance, we can provide a range of different finishes.
- Metallic Coatings: nickel/zinc/zinc-nickel/chromium
- Conversion Coatings: anodizing, phosphating, and chromate conversion coatings
- Organic Coatings: epoxies, polyurethanes, acrylics, and polyesters
- Salt spray
