FHSM & FHSI SERIES
FULL-HEXAGON WITH SMALL FLANGE RIVET NUT
HEX FLANGE,ROUND INTERNAL HOLE, OPEN END

 

The key advantage of the FHSM (Small Flange) and FHSI (Large Flange) series lies in their full hexagonal bore design. When installed into a pre-punched hexagonal hole, this design provides extremely high resistance to torque, completely eliminating the possibility of the rivet nut spinning or slipping during the tightening process. It ensures long-term stability for threaded connections subjected to high stress or frequent disassembly. The choice between large and small flanges depends on the panel thickness and load requirements.

The core of the SEM Small Flange Rivet Nut design lies in its low-profile appearance. The head protrudes minimally after installation, maximizing surface flushness and effectively reducing interference with adjacent components. It is typically used in applications where aesthetics are critical or assembly space is limited. Although the bearing area is smaller, it provides a standard threaded connection point, making it an ideal choice for solutions requiring basic fastening and pursuing a lightweight design.

The BEM-C and BAI-C series combine the advantages of the large flange design with waterproofing capability. The large flange maximizes the bearing surface against the parent material, effectively dispersing stress and enhancing pull-out strength, especially for soft or thin panels. The under-head sealant forms a robust waterproof layer after installation, ensuring that liquid and moisture do not penetrate through the hole. This provides a reliable solution for applications requiring both high structural strength and environmental protection.
