SMW 1/4" Fixturing Pin

Quality part.

These work excellently with Thorlabs "optical breadboard" (aluminum plate with 1/4-20 holes on 1" spacing). We happened to get a large Thorlabs plates donated to our student machine shop, and I wanted some alignment pin holes. I was torn between drilling/reaming out some of the threaded holes into alignment pin holes, making new holes in between the threaded ones, or... [enter Saunders Machine Works] just screw 2 of these into the bottom of the plate to make alignment with our t-slots easy, and then two of them sticking up from the top of the plate to drop parts onto. Problem solved! Thanks, SMW

Work great with our SMW fixture plates!
