Rivet Nut – Flat Head Semi-hexagonal Body, Open Type

The Rivet Nut, Flat Head Semi-hexagonal Body, Open Type is an innovative riveting fastener designed for efficient assembly and reliable rotation resistance. It skillfully combines the flush appearance of a flat head, the superior anti-rotation performance of a semi-hexagonal body, and the through-connection convenience of an open-end.

Its unique semi-hexagonal body design locks firmly into the base material after riveting deformation, providing torque resistance comparable to a hex nut, while offering significantly lower installation resistance than a full-hexagon rivet nut. This achieves an ideal balance between reliable anti-rotation and installation ease, making it a perfect choice for automated assembly lines and applications requiring efficient anti-loosening solutions.

Technical Parameters

▪Material Available – Carbon Steel, Stainless Steel, Aluminum.

▪Products Sizes – M3-M12 (Metric), 6#-1/2″ (Imperial). Or customize your size.
