Torque support grub screw – M6
The M6 grub screw is the headless hex socket screw that goes into the rear mount of a Booda Bike frame together with the torque support nut on Rohloff and 3X3 bikes – a part of our own design for our own frame.

Why this screw?
Made for the Booda Bike frame. It is our own part, so it matches the M6 thread of the frame's rear mount.
With the torque support nut. On Rohloff and 3X3 bikes, the torque support nut and this grub screw are fitted to the frame together.
A small spare worth keeping. Handy to have on the shelf for workshop jobs on the rear mount.
How is it fitted?
- On a Rohloff or 3X3 bike, fit the torque support nut and this grub screw together in the frame's rear mount.
- With a rack, the rack's screws are used on both sides instead (see the rear rack mounting screws).
Who is it for?
- Owners of a Booda Bike with a Rohloff or 3X3 hub. Who need to replace a lost or damaged grub screw.
- Workshops. That service Booda Bike frames.
