I currently have the bulk of my engine tin off and have ruined a few of the cheesehead screws. I am contemplating whether or not to simply buy some new cheeseheads from the local VW place and make sure to use anti-sieze on them, or should I replace the cheeseheads with another type of fastener altogether.

Any suggestions? BTDT?

The one's at the VW shops are pretty cheap. They are chrome and are real soft.

I've used standard hex heads bolts and used allen head bolts. I like the allen heads. The look cool and clean. You can find stainless steel ones at hardware stores or HD or Lowes.

Looks like we have consensus about allen head cap screws. There are different lengths though, but I guess that doesn't really matter when you are just attaching 2 pieces of tin together - more so when you re-attach the impeller housing to the case.

6mm x 1. VW went to Phillips head screws for the tin in 77 and up, a pretty satisfactory move. As others have said, there are several lengths to consider, but most of the screws are about 12mm long. The Cap'n

Doesn't stainless steel and aluminum set you up for some pretty nasty electrolosis? The stainless steel screws in the aluminum mast of the sailboat always make a mess... Not that I know of anything better, but some anti-seize and a steel screw may be "just as good".

That may be a problem in about 100 years.

Actually,

It's iron and aluminum that cause the iron to rust. The high nickle content in stainless prevents the iron form rusting.

I've seen bolts (used in oceanography) made from an iron/aluminum mix that are designed to corrode in seawater. Bolts are time designed to break after immersion. Attach a buoy to an instrument package with a bolt, chunk it over the side and come back in a week. Bolt corrodes and the bouy floats up so you can find it.

Accurate within 15 minutes. (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif)

Just FYI.

I went to my local Home Depot yesterday. In thier specialty bolt section they had 6mm x 12mm allen head screws, black, two to a pack. Cost was $1.12 per pack.

I bought all they had, about twenty, $11.82 for all.

You can buy a special thread lube in a tube at a boat rigging shop that will minimize this effect...West Marine may have it. Probably not worth worrying about though.
