Precision Fastener Prototyping - CNC Machined Stainless Steel, Carbon Steel & Coated Components
Product Overview
We specialize in high-precision, rapid prototyping of custom fasteners, offering CNC-machined solutions in stainless steel, carbon steel, and specialty-coated materials. Ideal for industries requiring tight tolerances, complex geometries, and fast turnaround, our prototyping services bridge the gap between design validation and full-scale production.
Key Features & Benefits
✔ Wide Material Selection
Stainless Steel (304, 316, 17-4PH) – Corrosion-resistant for harsh environments
Carbon Steel (Grade 4.8–12.9) – High strength for structural applications
Specialty Coatings – Zinc galvanized, tin-plated, nickel, or black oxide for enhanced durability
✔ Precision CNC Machining
Tolerances: ±0.01mm (standard) | ±0.005mm (high-precision)
Processes: Turning, milling, threading, broaching, knurling
Surface Finish: Ra 0.4–3.2μm (mirror polishing available)
✔ Fast Prototyping & Low-Volume Production
Lead Time: 3–7 days for prototypes | 10–15 days for batches (50–1,000pcs)
No MOQ: Accept 1-piece prototypes to small-batch orders
✔ Customization Options
Thread Types: Metric, UNC, UNF, or custom profiles
Head Styles: Round, flat, hex, socket, or proprietary designs
Secondary Processing: Heat treatment, passivation, laser marking
✔ Quality Assurance
100% Dimensional Inspection (CMM, optical comparators)
Material Certifications (MTC, SGS, RoHS)
Performance Testing: Salt spray (500+ hrs), torque/shear force validation
