Custom Threaded Pins with Tapered Tip and Precision Machined Finish for Threaded Locating Pins

Custom precision CNC-machined threaded locating pins are high-precision metal components manufactured according to customer engineering drawings. These parts can feature designs such as cylindrical bodies, external threaded sections, tapered tips, and localized flat surfaces—tailored for mechanical assemblies that require specific positioning, fastening, clamping, or assembly functions.

Shenzhen Hongsinn Precision specializes in the OEM/ODM manufacturing of custom, non-standard precision components. Based on 2D engineering drawings, 3D CAD models, or qualified samples provided by the client, we evaluate the optimal manufacturing processes—including CNC turning, thread machining, and milling—to deliver services ranging from prototype development and small-batch trial production to full-scale mass production.

For small, precision-threaded components, we focus on strictly controlling critical parameters—such as thread dimensions, body diameter, taper angle, effective length, concentricity, and surface quality—to ensure the parts meet all assembly and fitment requirements.

• 1. Precision External Thread Machining

  Customization of thread specifications, pitch, effective length, and fit requirements is available based on your technical drawings. Thread standards—such as metric, imperial, or other specified types—can be selected according to your requirements.

• 2. Tapered End Design

  Ends can be machined into tapered, radiused, or other specified profiles to meet design requirements. The shape and dimensions of the end are determined by the component's specific positioning, contact, or assembly functions.

• 3. Cylindrical Body with Flat Sections

  The main body can be machined to specific diameters and lengths, with integrated flat sections or gripping surfaces, to facilitate installation, adjustment, and the use of tools.

• 4. Precision CNC Machining

  Depending on the product structure and production volume, we utilize CNC turning, thread machining, milling, and other appropriate processes to ensure all dimensional and structural specifications are met.

• 5. Material and Surface Treatment Options

  We offer a range of materials—including carbon steel, alloy steel, and stainless steel—selected based on the operating environment, corrosion resistance needs, and mechanical performance requirements. Surface treatments are determined by the material, assembly clearances, and specific service conditions.

• Automation Equipment: Used for positioning, connecting, mounting, or adjusting components within automation equipment, depending on the specific structural design and functional requirements.
• Tooling, Fixtures, and Positioning Mechanisms: Suitable for tooling, fixtures, and mechanical positioning mechanisms that require threaded fastening, localized clamping, or specific end-point positioning.
• Precision Mechanical Assembly: Utilized for threaded connections, assembly positioning, or structural mating of mechanical components, ensuring compliance with specified dimensions and assembly requirements.
• Industrial Equipment and Specialized Machinery: Applicable to components in industrial equipment that require specialized threaded connections or custom-designed end structures; actual application should be verified against operational loads and environmental conditions.
• OEM/ODM Custom Part Projects: Suitable for sample development, small-batch trial production, and mass production projects for manufacturers of mechanical and automation equipment, fixture producers, and purchasers of precision components.
