DIN 1587 Hexagon Domed Cap Nuts China Factory Leading High Type Acorn Nut Suppliers
LONGZE DIN 1587 Hexagon Domed Cap Nuts, widely recognized as High Type Acorn Nuts, are engineered to provide a superior blend of aesthetic elegance and industrial protection. Featuring a deep internal cavity and a distinctive rounded top, these fasteners effectively shield protruding bolt threads from external damage, preventing snagging and ensuring a clean, professional finish for exposed joints.
As a core component of the LONGZE GFM-WCR System, these nuts are precision-manufactured for high-performance applications in architectural steelwork, automotive trim, and consumer electronics. By maintaining strict structural thread integrity across metric assemblies, we ensure that your projects benefit from both long-term corrosion resistance and a sleek, safe visual profile.

Frequently Asked Questions
DIN 1587 is a High Type Acorn Nut with a deeper dome and internal cavity, providing more coverage for protruding bolts, whereas DIN 917 is a Low Type/Blind Nut with a flatter profile.
We utilize double-walled cartons with internal partitions or individual bagging for polished orders, secured with high-tensile wrap to eliminate vibration damage.
For marine applications, we highly recommend SS316 stainless steel. We use spectrometer testing to ensure the absolute purity of the material grade.
Yes, our technical department offers rapid prototyping and drawing verification via the GFM-WCR system for bespoke engineering requirements.
All plated batches undergo 48H-96H salt spray tests. Any finish failing our "Golden Standard" for mirror-grade integrity is 100% rejected.
They are primarily designed to match ISO 4017 and DIN 933 bolts, ensuring a clean finish over the bolt end.
