seat base screw loose

[StevenH]

I have noticed that my single seat from the 2:1 kombi (T6 2017) is only held on with one bolt.

I found another on the floor but it’s damaged so need to source spares.

It looks like an m10 tri-square about 15mm and says 3 F on the base. Feels light like aluminium but it could be steel?

Any help much appreciated. Photo here.

A magnet will show you whether its steel.

Just replace with socket cap (allen head) of the appropriate size - lots on ebay. I use Spalding Fasteners or Kays.
