Product Summary

Dài Round Head Solid Rivets are manufactured to DIN 660 Và ASME B18.1.1 standards, serving as a permanent mechanical fastener for aerospace, shipbuilding, construction, and heavy machinery.

Featuring a smooth hemispherical head, these Round Head Solid Rivets provide a high-strength, tamper-proof joint by deforming the shank end to create a second head, ensuring maximum shear resistance and

structural integrity.

• ✔ Permanent Structural Bond: Unlike threaded fasteners, Round Head Solid Rivets create a vibration-proof joint that cannot be loosened without destroying the fastener.

•  

• ✔ Superior Shear Strength: The solid shank fills the hole completely during installation, offering higher load-bearing capacity than blind rivets.

•  

• ✔ Multipurpose Material Range: Available in Steel, Stainless Steel, and Aluminum to balance weight, strength, and corrosion requirements.

• High Load Capacity – Ideal for safety-critical structural joints in bridges and aircraft frames.

•  

• Tamper-Proof Design – Provides a flush, aesthetically pleasing finish that is difficult to remove without specialized tools.

•  

• Excellent Sealing – When properly driven, the rivet expands to fill the hole, creating a moisture-resistant and airtight seal.

•  

• Standardized Precision – Fully compliant with Metric (ISO) and Imperial (ASME) head styles for global engineering projects.
