1/4" UNF, S/S Socket Flanged Button Head Screws
Hi all
Can anyone tell me where I can purchase 20 of these screws?
I recently bought a Super Ram off one of the forum members but when it arrived a few of the above screws which hold down the lid of the SR were missing, so I would like to buy a matching set.
Thanks in advance
Nick

But I've never heard of flanged button head. I think they're just regular button heads. I was selling stainless screw kits for the superram before and that's what I provided. (I bought them from mcmaster carr in bulk)

Thanks guys, both the suppliers seem to have them.
Apparently there are two thread patterns, 20 and 28 threads per inch, all I have to do now is count the number of threads per inch on my screws to ascertain whether they are 20 or 28 threads per inch.

I can't figure out why.
I have emailed them my requirements.

it measures 12mm (which +- 1/2") and it has 10 threads within the 12mm, so I am therefore assuming that it is 20 threads per inch and not 28 as mentioned by you?
Do you think i am asking for the incorrect thread type?

I have just measured and counted the one i have. Unfortunately i only have a metric ruler.

You said it was fine thread, not me. Fine thread is 28, coarse is 20.
I'll go check...

They're 1/4"-28 fine thread, 1/2" long.
I thnk I got this from Accel, and sold a half dozen to superram owners without any complaints. You need a 5/32" allen wrench to install them.
Also, UNF = Fine thread
