Resurrecting this thread because I'm at a loss for what I'm trying to do.
Impact Machine used M4 screws for the EPS Carry dots they installed for me. I measure the length as 9.4mm - no problem, I can file a 10mm length. My problem is the head diameter - I'm unable to find a Torx M4 screw with a head diameter of 6mm to 6.5mm (Holosun factory is ~6mm and the Impact screws are ~6.4mm). The closest McMaster-Carr I'm finding has an 8.4mm head. They're also zinc-plated, and while that's not a deal breaker I'd certainly prefer black oxide.
Is that a small enough difference to not matter because at worst it will just stand a bit proud while still working, or do I need something else? First time dot owner and I'm way out of depth with the screw part of it.
Hello,
New to the site, and have been reading this thread and others like it trying to make sense of all the different McMaster part #'s. And Honestly I have confused myself I have two Glock 43X's with EPS Carry. One is a direct milled JagerWerks and one is a MOS with CHPWS Adapter plate. I am trying to confirm I have my PN's correct. Any help confirming and or correcting my assumptions would be appreciated.
JagerWerks - Direct EPS Carry to 43X slide = 91253A147
MOS - EPS Carry to CHPWS Plate = 94414A723
MOS - CHPWS Plate to 43X Slide = 94414A712
Spare Battery screw = 91698A241
Thanks!
Does anyone know what thread spec Agency Arms is using on their AOS plate? I am talking about the screws used to mount an RMR onto the plate, not the plate to the slide.
I used both these screws to mount a Holosun EPS Carry to a Sig P365 X Macro slide with the separate rear sight.
I recommend the 8mm length for direct mounting and the 10mm length if you use the plate that comes with the sight. I ended up direct mounting with the 8mm screw.
This is the McMaster Carr info.

I used 10mm on my initial install and it worked fine, but I took the sight off for some reason and noticed some thread damage at the bottom and tried the 8mm. It seemed to bottom out with no thread damage so I stuck with that. YMMV.
