Precision Prototyping Fastener CNC Machining Parts in Stainless Steel / Carbon Steel / Coated material

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
