· Product Overview
These 304 stainless steel flanged cylindrical locating pins are high-precision assembly components engineered to deliver accurate positioning, alignment, and structural support for mating parts in mechanical systems. Featuring a stepped cylindrical body, an integrated flange (to prevent over-insertion and enhance mounting stability), and a smooth inner bore (for optional secondary fastening), they combine corrosion-resistant 304 stainless steel construction with micron-level dimensional accuracy. Ideal for high-tolerance assemblies, these pins ensure consistent part alignment across repeated use—making them a reliable choice for industrial, electronic, and precision machinery projects.
· Core Specifications
- Material: 304 Stainless SteelOffers excellent corrosion resistance (suitable for indoor/outdoor dry/mild-moisture environments), high tensile strength (≥515 MPa), and compatibility with precision assembly processes.
- Manufacturing Standard: ISO 9001-Certified Precision CNC Turning Process
- Key Processes: CNC turning (flange, cylindrical body, inner bore) → Surface passivation (enhances rust protection) → Deburring (smooth edges for safe handling).
- Key Parameters:
- Standard Dimensions: Diameter = 8–15mm, Length = 15–30mm (customizable)
- Dimensional Tolerance: ±0.01mm (ensures tight fit with mating part holes)
- Flange Diameter: 2–3mm larger than pin body (for stable positioning)
- Performance Rating: Shear strength ≥300 MPa (varies by pin diameter).
· Application Scenarios
These flanged locating pins are widely used in high-tolerance assemblies:
- Industrial Automation: Robotic arm joint alignment, conveyor system part positioning, and actuator component mounting.
- Precision Machinery: 3D printer frame alignment, CNC router part fixtures, and mold tooling positioning.
- Electronic Equipment: PCB module alignment, server chassis component fastening, and communication device internal part spacing.
- Tooling & Fixtures: Workshop jig positioning, inspection tool part alignment, and production line component fixtures.
- Automotive Components: Small part alignment in interior trim assemblies or engine subcomponent mounting.
· Production Process Introduction
- Raw Material Sourcing: Procure 304 stainless steel bars (metallurgically tested for purity and mechanical performance).
- CNC Turning: Use precision CNC lathes to machine the integrated flange, cylindrical body, and smooth inner bore (per exact dimensional specifications).
- Surface Passivation: Apply a chemical treatment to boost the stainless steel’s natural corrosion resistance.
- Deburring: Remove sharp edges (for safe insertion into mating parts) and inspect surface smoothness.
- Quality Inspection: Conduct CMM (Coordinate Measuring Machine) scans to verify dimensional tolerance; test shear strength to confirm performance.
- Sorting & Packaging Prep: Group pins by diameter/length for organized inventory.
· Packaging and Shipping Methods
- Packaging: Individual pins are sealed in anti-scratch plastic bags; bulk orders are packed in foam-lined partitioned boxes (prevents pin deformation and surface damage during transit).
- Shipping: Flexible logistics options:
- Express Delivery (DHL/FedEx/UPS: 3–5 business days)
- Air Freight (7–10 business days)
- Sea Freight (20–30 business days)All shipments include full tracking and damage insurance.
· Process
· Frequently Asked Questions (FAQ)
- MOQ (Minimum Order Quantity): 500 pieces per diameter/length specification; small sample packs (20–50 pieces) are available for fit testing.
- Lead Time: Standard lead time is 7–10 working days after order confirmation; expedited production (5–7 working days) is available for urgent orders (additional fees apply).
- Customization Capability: Full customization is supported—we can adjust pin diameter/length, flange size, add external threads (for secondary fastening), or switch to 316 stainless steel (for harsh environments) based on your technical drawings. Our CNC team will validate design feasibility for assembly alignment.
