Been trying and failing to find a bolt that fits and have not had too much luck. don't want to force any old bolt's down into the subfloor.

Thanks!

The Katalog says its a 6mm x 16mm, standard thread is x 1.0.
"900 075 057 02 hexagon-head bolt M 6 X 16"

I use SS Phillips head machine screws. The factory bolts get crusty from wet shoes.
