DIN 1587 Hexagon Domed Cap Nuts (High Type Acorn Nuts) Manufacturer
LONGZE DIN 1587 Hexagon Domed Cap Nuts, widely recognized as High Type Acorn Nuts, feature a deep internal cavity and a distinctive rounded top to provide comprehensive protection for protruding bolt threads. As a critical aesthetic and safety node in the LONGZE GFM-WCR System, these nuts are precision-manufactured to prevent snagging and protect against corrosion in exposed joints. Whether utilized in architectural steelwork, automotive trim, or consumer electronics, our DIN 1587 series ensures a clean, professional finish while maintaining structural thread integrity across metric assemblies.
Optimal factory-direct assembly for decorative and protective joints:
- 🔹 Primary Match: ISO 4017 / DIN 933 Bolts
- 🔹 Locking Alternative: ISO 10511 (Nylon Lock Cap)
- 🔹 Low Type Alternative: DIN 917 (Blind Nuts)

🛡️ LONGZE STRATEGIC RISK MANAGEMENT & RESILIENCE
Ensuring aesthetic perfection and thread safety for the most demanding visual and functional applications.
- Scuffing: Automated soft-handling systems prevent metal-on-metal contact post-polishing.
- Dome Collapse: Thickness monitoring for the dome cap prevents deformation during heavy torque.
- Thread Jamming: Blind-hole cleaning protocols ensure no plating salts or burrs remain at the bottom.
- Material Verify: Spectrometer testing ensures SS316 vs SS304 identification for marine orders.
- Production Logic: Dual cold-forming and CNC machining capabilities for standard and custom sizes.
- IP High-Intent: Prioritized buffer stock for high-demand M6, M8, and M10 chrome-plated series.
- Logistics: Precision DDP duty calculation for Turkey, Malaysia, and Argentina shipments.
- SOP Control: All TDS production follows the LZ V2 Master template for data integrity.

Quality Assurance & Global Logistics Risk Control
Where technical precision meets global distribution. Every DIN 1587 nut is a testament to LONGZE manufacturing excellence.
Q: What if the chrome plating shows pitting or yellowing?
A: Surface integrity is our red line. We perform 48H-96H salt spray tests on all plated batches. Any finish failing our aesthetic "Golden Standard" is 100% rejected. We guarantee a mirror-grade finish.
Q: How do you ensure the nuts aren't damaged in transit to Istanbul?
A: Cap nuts are sensitive. We use double-walled cartons with internal partitions or individual bagging for polished orders. Pallets are secured with high-tensile wrap to ensure zero vibration damage during ocean transit.
