I have scoured the internet and this Forum to no avail. Does anyone know what size and thread pitch the bolts to mount the running boards to the body are on a 2001 Expedition.

Ford part # is N806528-S301 (I think). Got a deal on boards but no bolts and don't want to pay the stealership $8.00 a bolt (US probably double here in Canada) When there probably $1.00 at Fastenal

 

-N806528-S301 - Ford BOLT

They're only $2.52 each, not $8. To me it's worth a couple of extra buck to make sure I have the right grade and also due to the exposure to corrosion.\

Another option is to buy just one as a sample to measure the pitch and size.

 

They do not ship to Canada
