Looks like a radial pin.
lucasi. radial pin. the diameter is 3/8 of an inch.
schon. 5/16 -14
f.y.i. - when counting threads, you count how many threads per inch (t.p.i.)
how much are you looking to raise from raffling your lucasi?
just a word of caution...
... make sure you don't overcharge for spots.
"price per spot" x "# of spots" = market value of item raffled [not retail price]
