Rohloff Hub cap screw
Rohloff Hub Cap Screws (8237) are the genuine M4x10 Torx screws that hold the hub cap on the SPEEDHUB 500/14 – also used for the cable box cover of the external gear mech.
Why genuine screws?
Exact size. M4x10 with Torx TX20 head, tightened to 3 Nm according to Rohloff. 
Full set. A SPEEDHUB uses 8 or 9 hub cap screws, depending on the version. 
Fresh heads. Replace screws with damaged Torx heads before they become impossible to undo. 
Keeps the hub sealed. Evenly tightened screws hold the hub cap properly in place.
Who is it for?
- Owners with damaged screw heads. A rounded Torx head is a common reason to replace them.
- Workshops. Standard spares for SPEEDHUB service and cable box covers.

Frequently asked questions
Why does Rohloff recommend a T-handle key?
You need enough pressure into the Torx socket so as not to damage the screw head. Rohloff notes this is only reliably achieved with a T-handle key; L-keys can damage the heads.
How many screws are in the pack?
The pack is pictured with 9 screws. If you need a specific quantity, ask us.
