Socket Head Screws for Oil Filter Housings

[gazunni]

Does anyone know what material the socket head screws for the oil filter housing are made of, stainless, carbon or something else?

good question

I just took mine out last night and I couldn't tell you. Didn't feel light enough to be aluminum, but I cannot tell for sure:dontknow:. Seems like steel would have rusted though. I am interested to see the answer you get.

Depends..!

if you are talking about the bolts that hold the oil filter covers on..they are steel. All the bolts and screws used on engine cases are steel. Many are dipped unichromed and some are stainless...:thumbup:

Most likely steel alloy.

Why?

Just wondering if I can pick up at the local auto store or need to orderfrom BRP. My concern is with dissimilar metals and the aluminum block.

Most likely steel alloy.

Why?

Do not use black oxide plated,they will rust.

They are soft steel. I had a couple of the bolts where the hex got reamed out due to improper tool or tightened too much. I went to local hardware and got replacements.
