Among other things that I have been working on I have managed to order a large box of these fasteners.

I ruined my original screws upon removal as water collects on the back side. Fighting the rust and poor screwdriver choice you will see what I was left with.

The original fastener is a M4x.7 pitch 10mm long phillips machine screw. The screws that I have purchased are only 8mm long. I will say that I am trying to save weight where I can, but the truth is I miss-ordered. They work fine. They are 304 stainless steel; factory was zinc plated steel.

$2 to your door (lower 48) for a set of 4; Free if you pick them up.
