Custom Fasteners

We adopt various thread processing technologies including thread rolling, flat die rolling and turning, and supply high-end fasteners made of common aerospace materials such as carbon steel, aluminum alloy, copper alloy, superalloy and titanium alloy with comprehensive one-stop fastener supply capacity. Our product range covers pins, lock washers, gaskets, nuts (self-locking nuts, high-locking nuts), bolts, etc. Our high-strength products cover a tensile strength range of 900–1500 MPa.

1. Materials

Stainless Steel: 304, 316L, 17-4 PH (excellent chemical corrosion resistance).

Alloy Steel: 4140, 4340 (high strength, suitable for heavy-duty machinery).

Aluminum: 6061-T6, 7075-T6 (lightweight, ideal for aerospace and electronics).

Brass: high thermal conductivity and excellent machinability, suitable for fluid control.

2. Technical Highlights

Thread Precision: Supports a wide range of precision thread standards (Metric, NPT, BSPP, UN/UNF), with tolerances up to Class 3A/6H.

Surface Treatments:

Yellow Zinc Plating: provides superior rust protection and high visual recognition.

Anodizing: improves wear resistance of aluminum parts.

Passivation: enhances oxidation resistance and stability of stainless steel.

Sealing: Precision conical or stepped surface design ensures zero-leak connections under high pressure.

Process: High-precision CNC turn-mill machining, ensuring one-shot forming and concentricity for complex structures.

3. Industry Applications

Aerospace & Defense: Fuel system connections, sensor brackets, and structural fasteners.

Hydraulic & Pneumatic Systems: High-pressure hydraulic fittings, fluid distribution manifolds, and control valve components.

Automotive Engineering: Fuel systems for modified vehicles, brake system ports, and precision engine connectors.

Renewable Energy: Connections for hydrogen storage equipment and precision pivots for solar tracking systems.
