They are from Dymond hobbies, here in San Diego but are made in Germany. A bit longer than the Proctor, although Proctor has some longer ones listed in their on-line catalog. Proctor's have 1-64 threads but these are 2mm. Here's a pix of the packaging (5 units/pack @ $9.60).
A little bit of filing and they would make very scale-like clevises.
