Screws for aluminum slider

FIRST General Forum

In the 2012 KOP there is about a 2 foot long aluminum extrusion with a plastic slider in it that takes 2 screws. We are using this in our robot this year. I want to pick up some screws for that slider on the way home from work but I don’t know what thread size they are.
I was hoping one of you might be able to tell me?
Thanks

We had the same problem with year during FTC. I believe they are metric. I had to take the slide to lowe’s with me to size them.

They are M4.

Is it the rail from the IGUS bag? We used it a couple of years ago and if I remember right it was 4mm but can’t remember the pitch. To be sure check the IGUS website I think they have an online catalog.

M4 has two recognized pitches, .5mm and .7mm, but only the .7 is commonly used. If something specs an M4, they probably mean an M4x.7.
