Need to find Clean Factory 116505 - movement hold down screws

[dww0311]

Need advice on what size these would equate to and where might be the best place to source them from (Cousins, etc). Any assistance appreciated. I had one take a moon shot earlier and despite best efforts, this one in particular wants to stay lost. Ruler in pics is mm scale

I think what you are looking for is Rolex part 4130-5000 but @dogwood would know best.

Best option is to just buy a set of assorted case clamp screws from Amazon or cousins UK. I can’t remember exactly what size you want for the dd4130, but it’s slightly larger than 0.6mm and I’m pretty sure it’s small than 1.0mm so get an assorted pack of m0.6 m0.7 m0.8 m0.9 and m1.0 and you should be covered for this and the next movement you work on. Also, a set of digital calipers costs $20 on Amazon and is probably the best money I ever spent on a tool.

Found these on Ali, bit expensive for two screws and clamps mind you.

It turned out to be a 4130.166. Same case screw they use for several other movements. Ordered a pack of 5 for £12.10 including shipping. Cousins is amazing

Thank all of you for the help!!
