The M6-25BTL with threadlock is a black coated metal bolt that is used to assemble 17 of the 18 different connectors in the Flexpipe system. This bolt comes with solution used to seal (lock) fastener assemblies together to prevent accidental loosening of fasteners over time.

The best reason to use a threadlocker solution is to prevent the accidental back off of fastener assemblies due to vibration. We suggest using a threadlocker solution any time an assembly is going to be under strain or vibration.

We don't recommend that you use this part with the M6-N nut to connect anything other than the Flexpipe system.

Installation Steps
See the installation steps tab to view how to assemble this bolt.

Technical Information:
This bolt is fixed to the M-6N using a 5mm T-HANDLE allen wrench.
(It is essential that the bolt is tightened between 12-14 N.m torque.)

Antistatic Version (ESD):
Be sure to select the antistatic version M6-25BWZTL for all the ESD connectors. This version is nickel-plated to provide the same ESD characteristics as the Nickel Plated joints.

  1. Ensure you have the following parts:
    • 1x Joint set of your choice
    • (1-4)x M6-25BTL bolts (depending on Joint set)
    • (1-4)x M6-N nuts (depending on Joint set)
    • (2-5)x 28mm pipes of your choice (depending on Joint set)
    • 1x T-HANDLE 5mm hex key
  2. Group connectors around corresponding pipes.
  3. Make sure to put the bolt on the most accessible side and insert the smaller diameter of the nut into the corresponding hole.
  4. Loosely tighten all M6-25B bolts and M6-N nuts by putting them in the corresponding openings of the particular joint set.(Press the nut into the connector using your finger tip and turn the bolt into the nut with other hand).
  5. Fully insert all pipes
  6. Tighten completely the M6-25BTL and the M6-N together until the Joint set is firmly attached to the pipes. A force between 12-14 Nm is recommended for this step.
