Default Stainless Steel hardware and aluminum.

I was looking for some Stainless Steel self-drilling screws to mount the new rod holders I just got. I was looking on McMaster.com. They had 401 SS and 18-8 SS screws. Burning the notes for the 410 SS screws is says not for use with aluminum. Really narrowed down the selection of screws to only 1 in the size I need. Just a note... Not all Stainless Steel is OK to use with aluminum.

JBird,
I will say that I don't use self drilling screws for mounting much of anything.

So much better and easier to use one drill with a pilot drill bit and one drill to set the screw.

I never found any issue with any conventional stainless steel screw to use with aluminum.

Good luck

Jbird68,

I want to share an experience with you so that you don't repeat it. I was mounting some forward cleats on my aluminum gunnels. I drilled the four holes for each cleat and put in the screws one by one as I drilled the holes. Instead of using a screwdriver though, because they were really tight and I didn't want to risk drilling too big, I used my 12 volt impact driver. I snapped the last screw. That is a sound that you never want to hear when working with stainless screws. This is when I found out how hard stainless steel screws really are! I removed the cleat and tried to grip it with a vise grip....no luck. Then I tried centerpunching and drilling, then grinding. I even tried to punch it through the aluminium, nope. When all was said and done I was able to drill a hole next to the broken off one and get the cleat mounted. Looking at it, it looks normal other than one screw being a little crooked. The screws that I used had a sheet metal type tread on them, the same ones that Lund had used on the other cleats. If I had to do It over again I would have drilled, then tapped threads into the aluminium and used SS machine screws. I have used stainless steel self tapping screws for mounting cargo net hooks into the underside of the gunnels with no problems. Unfortunately they had a round head instead of the bevel head needed for the cleats.

I ended up buying stainless steel screws and drilling the holes with a drill first. Did not have the self tapping screws at the local hardware store.
