Double End Locating Pin with Two Small Shaft Tips Precision Turning Brass Dowel

This precision brass locating pin is fully manufactured by our in-house CNC automatic lathe turning process as an OEM custom part. Crafted from high-purity brass raw material, the workpiece features one main cylindrical body plus two concentric small-diameter pilot shafts on both ends. After precision machining, all items go through strict degreasing cleaning to remove residual cutting fluid, followed by brass passivation surface finishing to boost anti-corrosion performance and retain bright metallic appearance.

As experienced custom manufacturer, we provide all-in-one OEM custom service covering:

• Custom dimension redesign & production based on client’s technical drawings or physical samples
• Custom raw material grade replacement (various brass alloy grades available)
• Custom tolerance adjustment per client’s assembly requirement
• Alternative custom surface treatment besides standard passivation (polishing, nickel plating on demand)
• Flexible order quantity: prototype small batch trial order & large-volume mass customization

• High coaxial precision solves end pin deflection & assembly misalignment of cheap non-CNC processed pins
• Standard passivation finish avoids brass oxidation & rust issue during long-term storage, reducing client’s defective inventory loss
• Strict controlled dimensional tolerance eliminates poor fit & assembly jamming trouble in downstream production
• One-stop OEM custom service saves clients extra costs for multiple scattered component suppliers
• In-house CNC production shortens custom sample lead time to fix client’s urgent prototype development schedule delay

• Raw material incoming inspection: brass material composition test before machining to avoid inferior raw material
• In-process full dimension sampling inspection with micrometer & optical detector during CNC turning
• Post-surface treatment appearance & anti-corrosion spot check after cleaning and passivation
• Finished product full random sampling for concentricity and size tolerance verification before packaging & shipment
• Custom QC testing standard available per client’s specified inspection requirement via OEM custom service

Q1: Can you make custom size brass locating pin different from the standard dimension shown?

A: Yes, as custom manufacturer, we accept full OEM custom service to adjust all dimensions against your drawings.

Q2: What is your sample lead time for custom brass pin prototype?

A: 3-5 working days for prototype samples after confirming your custom specification.

Q3: Is passivation finish the only available surface treatment option?

A: No, we offer alternative custom surface finishes like bright polishing based on your OEM demand.

Q4: What is your minimum order quantity for custom production?

A: Small trial batches are acceptable for custom orders, no rigid MOQ restriction.

Q5: Can you provide third-party inspection report for finished custom products?

A: Yes, we support customized third-party QC test per buyer’s requirement.
