Can somebody tell me what size and type of screw to use for the 4 bottom holes and ferrules of the back pad?

Thanks,
Buck

They are Phillips head self tapping sheetmetal screws, if the "ferrules" are the stand offs the screw protrudes about 1/2 in maybe a few mm more.

Sorry, no one has given you the definitive answer yet.

From what I can tell, they would be a M5.5x25 sheet metal screw.
You can buy these from places like Belmetric or McMaster-Carr or a local quality hardware store.

I've got 4 spare screws if you need them.
They are in usable condition.

Deja vu...

I asked the same question. After getting the “correct” answer, I tried that size and couldn’t grab threads. I just randomly tried a Sheetrock screw I had a box of on the shelf and it fit like a glove!

I know we were going to include with the new back pads, so I know Matt has the answer, I'll ask him to post up.

I have the AA Interior hardwear kit and it states M5.5 x 25 for the back pad screws.
