I bought a box of Challenge 5/8" panel pins today to top up my supply, but when I compared them (at home) with the existing ones there is a marked difference in the shank diameter. The new ones have a diameter of 1.41mm whereas the ones I've currently got are only 1.06mm in diameter.
What other kind of "panel" pin would be this thin? I can't remember where I got the original size from or the brand. I need the thin ones!
