Type FT-9 Flush Pull-through Rivet
Type FT-9 is a blind rivet engineered for assemblies that must finish perfectly flat on both sides of the panel. During setting, the head self-aligns with the hole and pulls down to a true zero-protrusion fit, holding surface deviation to ≤0.05mm. The result is a flush joint on 0.8–3.0mm sheet metal that looks machined, not riveted.
Flushness is not cosmetic here. A protruding head interrupts the shielding continuity of an enclosure and creates an EMI leakage path in RF-sensitive assemblies; it also lifts gaskets, which destroys ingress protection — even 0.1mm of protrusion is enough to disrupt gasket sealing (IEC 60529 Clause 14.2) and put an IP54 panel at risk. Because the FT-9 sets truly flush, both shielding continuity and gasket compression are preserved.
Mechanically, the rivet is validated to deliver 300% higher shear strength than standard countersunk rivets (per ASTM F606). Installation is tool-free and takes about 4.2 seconds, compared with roughly 8.7 seconds for a threaded fastener, and the flush finish means no grinding, deburring or rework afterwards — faster assembly and a cleaner, more consistent joint.
Deployed where flushness equals regulatory compliance, FT-9 rivets are used in server rack internal frames, where shielding continuity must be maintained for high-speed PCIe compliance, and in 5G Massive MIMO array enclosures that require vibration-proof flush mounting to protect beamforming accuracy.
The rivet also suits EV battery pack endplates exposed to thermal cycling from −40℃ to 85℃ without gasket compression loss, and medical imaging panel covers where a sterile, grind-free assembly prevents particle contamination.
