Product Specifications & Advantages

Feature	Details & Specifications	Benefit for PCB Application
Core Material	High-Purity Aluminum Alloy (e.g., 6061, 5052).	Lightweight: Reduces overall assembly weight. Non-Magnetic: Essential for RF and sensitive circuitry. Good Conductivity: Can aid in grounding.
Surface Finish	Matte Tin (Sn) Electroplating. Dull, non-reflective finish with consistent coating thickness.	Excellent Solderability: Tin provides a perfect surface for reliable hand or reflow soldering to PCB pads. Corrosion Resistance: Protects the aluminum base from oxidation. Low Glare: Matte finish minimizes light reflection in enclosed assemblies.
Types & Styles	Hex Nuts: Standard (DIN 934 thin) for standard fastening. Standoffs/Spacers: Hex or cylindrical, male-female or female-female, for board stacking or component elevation. Sizes: M2, M2.5, M3, M4 and other metric sizes as per demand.	Provides versatile solutions for component mounting, board-to-board spacing, and chassis attachment within electronic enclosures.
Key Dimensions & Tolerances	Precision machined to standard metric thread specifications (ISO). Tight tolerances on hex width and thickness ensure consistent torque and fit.	Ensures compatibility with standard screws and smooth assembly using tools. Reliable performance in automated or manual assembly lines.
Primary Applications	Securing terminal blocks, connectors, and modules to PCBs. Creating space between PCB and chassis for heat dissipation or clearance. Mounting points for sensors, displays, or small sub-assemblies. Used in consumer electronics, telecommunications, automotive electronics, and industrial controls.	Ideal for any electronic assembly requiring a lightweight, reliable, and solderable threaded fastener.

Why Choose ZHENGNA's Tin-Plated Aluminum Nuts?

Optimized for Electronics: The aluminum body reduces weight without sacrificing strength, while the matte tin plating ensures superb solderability and protects against corrosion in moderate environments.
Superior Solder Joint Reliability: Our controlled plating process guarantees a uniform, oxide-free tin surface, leading to strong, void-free solder joints critical for mechanical and electrical integrity.
Precision for Automated Assembly: Consistent dimensions and clean threads allow for easy integration with pick-and-place equipment and automated screwdriving systems.
Cost-Effective & RoHS/REACH Compliant: Aluminum is a cost-efficient material, and our tin plating process uses RoHS-compliant chemistry, making these nuts suitable for global electronics markets.
Full Traceability & Quality Control: From raw material to final plating, we maintain strict process control. Lot traceability is available for quality assurance purposes.

Our Manufacturing & Quality Commitment

Precision Machining: CNC machining ensures accurate thread geometry and dimensional consistency across all pieces.
Controlled Plating Process: Electroplating in automated lines to achieve a uniform, matte tin coating with specified thickness for optimal performance.
Rigorous Inspection: 100% visual inspection, sample-based dimensional checks, and adhesion tests (e.g., tape test per ASTM B571) for the plating.
ESD-Safe & Clean Packaging: Available in bulk or packaged in ESD-safe bags to prevent contamination and electrostatic damage for sensitive components.
