Brass Clamping Screw for Starrett V-Blocks

[PJs]

Nice work Paul. That patina is beautiful and hopefully your brass will catch up with it over time.

Would have thought a standard 1/4-28 would have worked but obviously they chose something slightly under although the machinery's hand book says the min. maj. diameter could be as low as .2392 for a class 1A...not so good for a V-block hold down. The oddest threads I ever worked with are the grip screws for a 1911 which are .1500-50 UNS-2A THD which screw into a threaded bushing with .2360-60 UNS-2A THD into the frame.

I guess if your name is Starrett or Browning you can do what ever you want. ~¿@ Nice work on yours and thanks for sharing!! ~PJ
