Product Overview

Our precision CNC threaded pin is designed for fastening systems, machinery assemblies, and industrial equipment where accurate threads, reliable fit, and stable mechanical performance are required. As a professional threaded pin manufacturer and threaded pin supplier, we produce these components using precision CNC turning and threading processes. Each CNC threaded pin can be customized according to diameter, length, thread type, and material requirements to meet exact customer specifications.

This product is suitable for assemblies requiring secure positioning and threaded connection. We support different metal materials including stainless steel threaded pin and carbon steel threaded pin options, with optional surface treatments depending on application conditions and customer specifications. As an experienced custom threaded pin provider, we support prototypes and volume production for global B2B buyers.

• Custom Sizes and Thread Types Available – metric, imperial, fine pitch, and special thread profiles

• Suitable for Fastening and Assembly Use – engineered for secure positioning and load-bearing connections

• OEM Production Supported – drawing-based manufacturing with custom branding and packaging

• Multiple Surface Treatment Options – zinc plating, black oxide, polishing, and passivation available

Technical Specifications

Materials and Manufacturing Process

This CNC threaded pin is manufactured by turning, threading, chamfering, and finishing operations according to drawing requirements. As a professional threaded pin manufacturer, we operate advanced CNC lathes with live tooling to produce accurate thread profiles and consistent quality for every precision threaded pin order.

Material options include:

• Stainless Steel Threaded Pin – SS304 / SS316 for excellent corrosion resistance in harsh and outdoor environments

• Carbon Steel Threaded Pin – high strength and cost-effectiveness for general industrial fastening applications

• Alloy Steel Threaded Pin – enhanced strength and wear resistance for heavy-duty machinery assemblies

• Brass Threaded Pin – H59 / H62 for decorative, electrical, and low-corrosion applications

Available surface treatments include:

• Zinc Plating – enhanced corrosion resistance for carbon steel pins in humid environments

• Black Oxide – decorative finish with moderate corrosion protection for indoor applications

• Polishing – smooth, reflective surface for aesthetic and low-friction threaded connections

• Passivation – chemical treatment to maximize stainless steel corrosion resistance

Applications

Our precision CNC threaded pins are widely used in:

• Fastening Systems – secure positioning, alignment pins, and threaded connections in mechanical assemblies

• Industrial Machinery – gearbox components, drive systems, and equipment fastening points

• Equipment Assemblies – frame connections, panel mounting, and structural joints

• Structural Components – load-bearing connections, support brackets, and alignment fixtures

• OEM Projects – custom machinery, prototypes, replacement parts, and specialized fastening solutions

• Automotive and Transportation – engine components, suspension systems, and interior fastening
