· Product Overview
These precision-engineered cylindrical connectors are crafted from H62 brass—an industry-standard material valued for excellent electrical conductivity, thermal conductivity, and wear resistance. Featuring a smooth, polished brass finish (natural golden luster) and a hollow internal bore (for shaft/line insertion), they are manufactured in batches with tight dimensional tolerances to ensure consistent fit across assemblies. Ideal for both electrical connection and mechanical lining applications, these connectors balance durability, functionality, and aesthetic appeal.
· Core Specifications
- Material: H62 BrassElectrical conductivity ≥20 MS/m, tensile strength ≥300 MPa, and good corrosion resistance (suitable for dry/mild-moisture environments).
- Manufacturing Standard: ISO 9001-Certified
- Key Processes: CNC Turning (cylindrical profile shaping) → Precision Drilling (internal bore) → Deburring (smooth edges) → Surface Polishing (natural brass luster) → Dimensional Inspection.
- Standard Parameters:
- Outer Diameter: 10mm (customizable 8–15mm)
- Length: 25mm (customizable 20–30mm)
- Internal Bore Diameter: 5mm (customizable 3–8mm)
- Dimensional Tolerance: ±0.01mm (ensures consistent assembly fit)
- Surface Finish: Natural brass polished (smooth, corrosion-resistant, and visually consistent).
· Application Scenarios
These brass cylindrical connectors are widely used in:
- Electrical & Electronic Equipment: Conductive terminals, circuit board connection pins, or signal transmission components.
- Hydraulic/Pneumatic Systems: Wear-resistant liners for small-diameter shafts, fluid line connectors, or valve component sleeves.
- Instrumentation & Meters: Precision component liners, sensor connection parts, or calibration device fittings.
- Industrial Assembly: Mechanical shaft connectors, small equipment lining sleeves, or DIY project connection components.
· Production Process Introduction
- Raw Material Procurement: Source certified H62 brass bars (compliant with material quality standards).
- CNC Turning: Use high-precision CNC lathes to shape the cylindrical outer profile in batch production.
- Precision Drilling: Machine the internal hollow bore (matched to target shaft/line dimensions).
- Deburring: Remove sharp edges from the bore and end surfaces (prevents assembly damage and ensures safe handling).
- Surface Polishing: Buff the outer surface to achieve a smooth, consistent brass golden luster.
- Quality Inspection: Verify dimensional accuracy (via calipers/CMM) and check for surface defects (scratches, burrs).
· Packaging and Shipping Methods
- Packaging:
- Individual units: Sealed in anti-static plastic bags (ideal for electrical application use).
- Bulk orders: Packed in foam-lined partitioned boxes (prevents collision and surface scratches) + reinforced cardboard outer packaging.
- 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 large-batch orders).All shipments include full tracking information and damage insurance.

· Frequently Asked Questions (FAQ)
- MOQ (Minimum Order Quantity): 1,000 pieces for standard dimension configurations; 500 pieces for custom designs (with valid technical drawings).
- Lead Time: Standard lead time is 7–10 working days (includes batch CNC production and polishing); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
- Customization Capability: We support full customization—adjust outer diameter, length, internal bore size, or add threaded features (for secure fastening) based on your requirements. Our engineering team validates designs for material compatibility and assembly fit.
