Core Product Advantages
Global universal standard
Manufactured strictly according to ISO 4034 international standard, fully compatible with global metric bolts. Ideal for equipment replacement, project maintenance and foreign trade supporting with zero threshold.
Grade 4/6 suitable for general load scenarios
Perfect for non‑heavy-load fastening positions, secondary steel structure connections and sheet metal assembly. It meets daily mechanical fastening requirements with lower cost and higher cost performance than high-strength nuts.
Precise thread for smooth assembly
Standard thread profile ensures smooth screwing without jamming or slipping, improving assembly efficiency for manual and automated production lines.
Complete specifications for bulk supporting
Full range of metric sizes covers precision equipment and steel structure applications, supporting one-stop bulk supply for container orders and project matching.
Multiple surface treatments
Various finishes adapt to indoor conventional assembly and outdoor mild anti-corrosion environments, meeting different project appearance and durability requirements.
Production Process
Material Selection: High-quality carbon steel with stable mechanical properties for grade 4/6 standard performance.
Cold Heading: Multi-station cold forging forming with standard hex size and flat end surface.
Precision Tapping: CNC threading ensures standard thread tolerance and smooth fitting.
Heat Treatment: Tempering treatment for grade 6 nuts to stabilize mechanical performance.
Surface Treatment: Zinc plating, black oxide and HDG finishes customized on request.
Final Inspection: Strict dimensional, thread and appearance sorting to guarantee stable batch quality.
Application Industries
General Machinery: Racks, workbenches and auxiliary equipment fastening.
Steel Structure Engineering: Secondary connection for brackets, guardrails and platforms.
Electrical & Sheet Metal Equipment: Control cabinet and equipment shell assembly.
Hardware Supporting: General hardware accessories and standard parts bulk supply.
Light Industry & Agricultural Machinery: Light-duty mechanical conventional fastening positions.
Installation & Usage Notes
1. Reasonable scenario selection: ISO4034 grade 4/6 nuts are designed for ordinary load conditions, not suitable for heavy-load, high-impact or key force-bearing positions.
2. Match standard metric bolts: Use with corresponding metric coarse thread bolts to avoid thread damage from improper assembly.
3. Control tightening torque: Avoid over-tightening to prevent nut cracking or thread damage.
4. Keep fitting surface clean: Remove burrs and impurities to ensure uniform stress and stable fastening.
5. Anti-rust protection: Choose galvanized or hot-dip galvanized versions for humid and outdoor environments.
