· Product Overview
This comprehensive assortment of precision slotted step pins and probes is engineered from brass, 304 stainless steel, and 6061-T6 aluminum—materials selected for their unique performance properties, including electrical conductivity, corrosion resistance, and lightweight rigidity. Each pin features a multi-stepped cylindrical profile with precision-machined slots, enabling secure retention, electrical contact, or axial positioning in high-performance assemblies. CNC-machined to ultra-tight tolerances and finished with protective surface treatments, these pins deliver reliable performance in applications where precision, conductivity, and durability are critical.
· Core Specifications
Material Performance
| Material | Key Properties |
|---|---|
| Brass (C36000) | Excellent electrical conductivity (≥16 MS/m), high thermal conductivity, and corrosion resistance in mild environments |
| 304 Stainless Steel | Superior corrosion resistance (72-hour salt spray pass), high tensile strength (≥515 MPa), and food-safe compliance |
| 6061-T6 Aluminum | Lightweight (2.7g/cm³), high rigidity (≥290 MPa), and excellent thermal conductivity (167 W/m·K) |
Manufacturing Standards
- Certification: ISO 9001-Certified
- Key Processes: CNC Turning (multi-stepped profile) → Slot Milling (precision retention slots) → Deburring → Surface Treatment (Nickel Plating/Passivation/Anodization) → CMM Inspection
- Standard Parameters:
- Diameter Range: 2–8mm (customizable 1–12mm)
- Length Range: 20–60mm (customizable 15–100mm)
- Slot Design: Straight/angled slots (optimized for spring retention or electrical contact)
- Dimensional Tolerance: ±0.01mm (ensures precise mating with sockets and fixtures)
- Surface Finish: Nickel-plated (brass), passivated polished (stainless steel), natural anodized (aluminum)
· Application Scenarios
These multi-material slotted step pins excel in precision connection, positioning, and sensing use cases:
- Electrical Connectors: Pin headers for PCB assemblies, power terminal contacts, and automotive wiring harness components.
- Test & Measurement Equipment: Probe pins for circuit board testers, voltage sensing contacts, and diagnostic instrument probes.
- Industrial Automation: Locating pins for conveyor systems, spring-loaded retention pins for fixtures, and robotic tool changer components.
- Medical & Laboratory Devices: Electrical contact pins for diagnostic instruments, sample handling system probes, and surgical tool positioning pins.
- Aerospace & Defense: Lightweight aluminum pins for avionics connectors, corrosion-resistant stainless steel pins for structural fixtures, and brass pins for high-frequency signal transmission.
· Production Process Introduction
- Raw Material Preparation: Cut certified brass, 304 stainless steel, or 6061-T6 aluminum bars into blanks matching the pin's overall length.
- CNC Turning: Use high-precision CNC lathes to machine the multi-stepped cylindrical profile in a single setup for maximum concentricity.
- Slot Milling: Create precision slots (straight or angled) to enable spring retention, electrical contact, or axial alignment.
- Deburring & Finishing: Remove sharp edges from slots, steps, and pin ends to prevent component wear and ensure safe handling.
- Surface Treatment: Apply nickel plating (brass) for enhanced conductivity, passivation (stainless steel) for corrosion resistance, or anodization (aluminum) for durability.
- Quality Inspection: Perform CMM dimensional scanning, slot fit testing, and surface finish analysis to verify compliance with design specifications.
· Packaging and Shipping Methods
- Packaging:
- Individual Pins: Sealed in anti-scratch, anti-static plastic bags and labeled with material/size specifications for traceability.
- Bulk Orders: Packed in foam-lined partitioned boxes (prevents pin deformation, slot damage, and mixing of materials/sizes).
- Shipping Options:
- Express Delivery (DHL/FedEx): 3–5 business days for prototype or small-quantity orders.
- Air Freight: 7–10 business days for medium-batch production runs.
- Sea Freight: 20–25 business days for large-volume bulk orders.All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)
- Lead Time: Standard lead time is 7–30 working days (includes CNC machining, surface treatment, and inspection); expedited production (5–7 days) is available for urgent orders (additional fees apply).
- Customization Capability: Full customization is supported—adjust diameter/length, slot geometry, material grade, or surface finish (e.g., gold plating for brass pins). Our engineering team validates designs for conductivity, retention force, and dimensional accuracy.
