Easy installation

Installing a Tubtara® blind rivet nut is very simple.

Select one of the Tubtara® blind rivet nuts from our extensive product range and a matching setting tool. Take a test workpiece and drill an appropriate hole.


Screw the Tubtara® blind rivet nut (A) on the mandrel (B) of the setting tool. In the case of the open version, the mandrel should protrude about 1 mm. For closed rivet nuts, continue screwing until you feel resistance. Screw the anvil (C) against the head of the Tubtara® and block it with the locking nut (D).

Step 1


Insert the Tubtara® blind rivet nut, mounted on the setting tool, into the hole of the workpiece.

Step 2


Set the Tubtara®. The Tubtara’s deformation chamber now forms the counter head (bulb) on the underside of the workpiece.

Step 3


Unscrew the mandrel from the Tubtara®.

Step 4


The Tubtara® blind rivet nut is now set. You can now easily insert your bolt or screw to assemble another component.

Step 5


Countersunk heads

Are you using a Tubtara® blind rivet nut with a countersunk head? Always countersink at 90° so that the head of the installed Tubtara® protrudes about 0.1 mm above your workpiece. This ensures direct contact with the assembled component.

Don’t have the possibility to countersink? Use a low profile head.

Setting dangers

  • Oversized hole (can affect setting & torque-to-turn)

  • Burr under the hole (can impact grip range)

  • Oiled/dirty hole (can affect torque-to-turn)

  • Incorrect hole shape for countersunk head (tightening bolt will loosen the Tubtara® blind fastener)
