Seal Inox® topcoat on stainless Tubtara’s prevents galling

Seal Inox Tubtara

Seal Inox is a thin topcoat applied on stainless steel Tubtara blind rivet nuts, making it easier to assemble stainless steel threaded parts.  It reduces friction and prevents gripping (galling) during assembly.  A cost saving solution reducing assembly time.
Seal Inox will also slow down contact corrosion and can protect against various chemicals.

Watertight solution: New Tubtara® with seal under the head

Watertight Tubtara

The non-reactive peripheral seal, made of flexible organic based material, that is applied to the under head bearing surface of a Tubtara rivet nut with flat head.
It reassures an IP 67 waterproof Tubtara-sheet assembly (guaranteed under Dejond test conditions).  During installation of the Tubtara, the material is gap filling, forming a robust seal between mating surfaces.
The seal is resistant to many automotive oils, antifreeze and transmission fluids.

Superior coldformed stainless A5/A6 TUBTARA's

stainless A5 A6 Tubtara

Sometimes even A4 fasteners in stainless 316 offer insufficient corrosion protection, like in civil engineering, tunnel infrastructures, ceiling panels in swimming pools etc.
Especially for these extremely demanding, chloride bearing applications, Dejond developed a new coldformed TUBTARA® blind rivet nut in high alloy austenitic stainless steel 1.4571 (A5) and 1.4539 (A6).

Samples available.

Anti-Turn Tubtara®

Anti-turn Tubtara

Can you only use or drill round holes?
Do you have an application in very hard or slippery material?

Use our Anti-Turn Tubtara® with special anti-rotation head and round shank to reach a torque-to-turn value at least twice as high as that of the equivalent round blind rivet nut.

Samples available.
