update - solved by @fskornia - it's a "presser foot screw".. ha!

fellow sewing machine nerds: i am resurrecting a Pfaff Select 1546 from the dead - a thrifting find last week. after 20+ hours of repair work, the machine is nearly done.

i have one last job: i bought a replacement presser foot attach/release assembly. it's supposed to screw into the top feed as shown, unfortunately the assembly didn't come with the screw! (pic 2, shown in red)

can anyone help me identify the screw? i couldn't find it in either the user or service manuals, and web searches are only showing screws for other machines. it would help to know even what the screw is called at this location.

Yes, indeed. If there is no documentation the first step is measuring the hole an finding candidates for the relevant thread (it is typically M4 coarse in this position both in Pfaff and Adler industrial machines. I don't know for the home market). Feel free to tell me the inside hole (you can measure it with a vernier ) and I can give you the candidates for the thread. If you want to do the search on your own you can have a look at any machinst's handbook or ISO-68-1
