'75 CB550 engine case screws
« on: April 24, 2011, 01:34:38 PM »
I drilled out the case screws on the clutch pedal side of my 75 cb550. I got 6mm allen head black screws from lowes for the top two, but they don't have any screws long enough for the bottom two.

Where can I get just 2 screws to put back into it?

Out here in California, I find Ace Hardware, and Do It Best stores have an excellent hardware selection. And when things get weird, there is specialty fastener supplier. Google hardware, or fasteners in your area.

Honda still sells these screws. They're only about 50 cents each.

In my experience the black oxide cap screws will rust eventually.
Do you have a copy of the Honda Shop Manual or Parts List for your bike? Get one here:

If you are replacing some engine case screws, why not just go ahead and replace them all?  That way you know they will all have a long life ahead of them.

I've found these to be great, and I bought a set for my 500.
