Hey friends, I’m using the expansion shell with an OCulink adapter and I was just wondering what size screw I need to secure this 3d printed back plate? I know I had one before but it has eluded me. I’d love to pick a new one up. ![20260802_085405-EDIT](https://us1.discourse-cdn.com/flex001/uploads/framework3/original/3X/4/1/4166362446cb30fd06102d325b831d1caa3ffadd.jpeg) Thanks for the consideration and have a great day! ---

So unfortunately I don’t have the information you’re looking for, BUT I do know there should be a spot inside the FW16 main chassis where there are extra screws. One of those might work. [FW16 Extra Screws](https://community.frame.work/t/extra-screws-included/67060/3) ---

Think it is supposed to be one similar to the ones on the left and the right side keeping the M2 board in place. (which are similar sized, I believe, to the ones required to assemble the interposer between the mainboard and the expansion bay) ---

Thanks for the replies, folks. Unfortunately, it doesn’t seem to be the same size as the screw holding the M.2 drives down. I tried one and it seems slightly too small and strips when I tighten it with any force at all. The extra screws is a cool idea, but if I’m being honest, I don’t really feel like partially disassembling the rig or removing parts to get to them. If anyone from the community or [@Framework](https://community.frame.work/groups/framework) team might know that screw size, I’d love to pick one up! ---

Wait, If this hole is not modded but officially part of the bare Expansion Bay shell it _should_ be somehere on this schematic, with its exact measurements already given. (or if not you can just take a ruler and measure the hole on the schematic and then calculate its precise size using the measurements taken and scale of the schematic): > **[FW\_UMA\_MODULE\_REF\_0.pdf](https://raw.githubusercontent.com/FrameworkComputer/ExpansionBay/main/Mechanical/ExpansionBayShell/FW_UMA_MODULE_REF_0.pdf)** > > 3.63 MB Then you will at least know what kind of screw you are looking for
