· Product Overview

• A flanged head (for axial load limiting and stable surface positioning)
• A split (slotted) cylindrical body (provides elastic tension to secure the pin in bores or shafts)
• A hollow internal structure (reduces weight while maintaining clamping force)CNC-machined and finished with passivation, these pins deliver quick, secure positioning for assemblies—ideal for applications requiring tool-free, reusable component fixation.

· Core Specifications

• Material: 304 Stainless Steel
  • Tensile strength: ≥515 MPa (rigid enough for clamping force)
  • Corrosion resistance: 72-hour salt spray test passed (suitable for humid/industrial environments)
  • Food-safe: Compliant with FDA 21 CFR 175.300 (optional for food-processing equipment)
• Manufacturing Standard: ISO 9001-Certified
  • Key Processes: CNC Turning (flange + cylindrical body) → Stamping (split slot) → Deburring → Surface Passivation
  • Standard Parameters:
    • Flange diameter: 12mm (customizable 8–15mm)
    • Pin body diameter: 6mm (customizable 4–10mm)
    • Pin length: 15mm (customizable 10–25mm)
    • Dimensional tolerance: ±0.02mm (ensures tight fit in target bores)
  • Surface Finish: Passivated polished (scratch-resistant, rust-proof, and smooth for easy insertion)

· Application Scenarios

• Electronics Assembly: PCB component positioning pins, enclosure panel alignment pins.
• 3D Printing Systems: Build plate alignment pins, extruder component fixation pins.
• Industrial Fixtures: Workbench jig positioning pins, tooling plate quick-release pins.
• Furniture Hardware: Drawer panel alignment pins, cabinet component fastening pins.
• DIY & Hobby Projects: RC vehicle part positioning, custom equipment assembly pins.

· Production Process Introduction

1. Raw Material Preparation: Cut 304 stainless steel tubing into blanks matching pin length.
2. CNC Turning: Machine the flanged head and cylindrical body to target dimensions.
3. Stamping: Create the split slot in the pin body (enables elastic clamping force).
4. Deburring: Remove sharp edges from the slot, flange, and pin ends (prevents assembly damage).
5. Surface Passivation: Apply chemical passivation to enhance corrosion resistance.
6. Quality Inspection: Verify dimensions (calipers/CMM) + check slot elasticity + confirm surface finish.

· Packaging and Shipping Methods

• Packaging:
  • Individual Units: Sealed in anti-scratch OPP plastic bags (prevents dust/rust during storage).
  • Bulk Orders: Packed in foam-lined partitioned boxes (avoids pin deformation, slot damage, and surface scratches).
• Shipping Options:
  • Express Delivery (DHL/FedEx: 3–5 business days for sample orders).
  • Air Freight (7–10 business days for small-batch production).
  • Sea Freight (20–25 business days for bulk orders).All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 1,000 pieces for standard configurations; 500 pieces for custom designs (with valid technical drawings).
• Lead Time: Standard lead time is 7–10 working days (includes machining and passivation); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—adjust flange diameter, pin body size, length, or modify the split slot design. Our team validates designs for clamping force and fit.
