Rub Rail and Metal Screws

[cameront120]

On the rub rail that covers where the exterior aluminum panels meet the belly pan, someone has replaced missing rivets with sheet metal screws. No doubt, these have created a larger diameter hole than originally needed for the rivets. Can I simply drill the hole out and install a new, larger diameter rivet to correspond with this new diameter hole?

Also, I keep seeing references to #21, # 11 & #30 drill bits. All of the drill bits I see in my local hardware stores are fractional. Does anyone know where I can get these numbered drill bits?

Thanks in advance.

Cheers

Cameron,

Inland RV had the number drill bits in a set of seven, I think, for about $8 US. However, they only ship orders totaling over $25, so you could order three sets or something else.

Cameron,

Number drill bits are in-between the fractional sizes. Look at a local machine shop supplier or go to www.mcmaster.com.

I am doing a aft end replacement on a 1997 and the factory has used long screws and rivets. Might use the long screws to draw the moulding into position for the rivets. I am in the take apart stage.

Did they stagger/alternate the rivets with long screws?

Thanks for the tips on the drill bits lewster and wkerfoot, I found a local machine shop supplier that has them in stock.
