Product Overview
This CNC machined stainless steel pin is designed for applications requiring accurate positioning and stable assembly performance. As one of our custom precision locating pins, the component is manufactured from ASTM 304 stainless steel and produced under controlled turning processes. The smooth cylindrical profile and rounded ends allow easy insertion while maintaining consistent alignment in mechanical and automation systems.
Product Construction
The part features a straight cylindrical body with symmetrical rounded ends, supporting reliable positioning during repeated assembly. Machined fillet radii are applied between functional surfaces to reduce stress concentration and improve durability. All edges are carefully deburred and broken to prevent damage to mating components. Diameters are processed on a common axis, ensuring stable concentricity for guide and alignment functions.

Manufacturing & Applications
Produced through CNC turning with stable tooling control, each part is inspected to ensure dimensional consistency and surface quality. These components are widely used as stainless steel locating pins, CNC turned alignment pins, and custom dowel pins in automation equipment, assembly fixtures, tooling systems, and mechanical positioning structures. The corrosion resistance of 304 stainless steel makes the pin suitable for long-term operation in industrial environments.
As a reliable supplier of custom precision locating pins, we support drawing-based manufacturing, small to medium batch production, and strict dimensional control to meet various assembly requirements.
FAQ
Q: Can you manufacture precision locating pins according to our drawings or samples?
A: Yes. We specialize in custom CNC machining based on customer drawings or physical samples. Dimensions, tolerances, surface requirements, and material specifications can all be produced according to your project needs.
Q: What tolerance range can you hold for locating pins?
A: For precision locating pins, we are able to control tight diameter tolerances, concentricity, and runout based on drawing requirements. Typical tolerance capability can reach ±0.01 mm or better, depending on part structure and inspection method.
Q: What materials are available besides ASTM 304 stainless steel?
A: In addition to ASTM 304, we can machine locating pins from 303, 316 stainless steel, carbon steel, alloy steel, aluminum, or other specified materials. Material certificates can be provided upon request.
Q: Do you support small batch or prototype orders?
A: Yes. We support prototype, small batch, and mass production orders. This allows customers to verify fit, function, and assembly performance before moving into full production.
Q: How do you ensure quality consistency for batch production?
A: All precision locating pins are produced using stable CNC turning processes and inspected during production. Critical dimensions such as diameter, runout, and surface condition are checked to ensure consistency across batches.
