$7/screw, do they at least give you a reach around? The fuck? Looks like a pretty standard M3x4 with a Torx head.
I might have some of those hiding in my stock room here at work. Probably
M3X4 with a t8 or t10 driver size. If I find them I'll let Lobster know. They probably wont be black oxide coated, however, just a plain bare stainless finish. And they wont be $7/screw, either.
