I have previously purchased two types of nuts from this company and none of them were listed. The first was not a "slight protrusion" larger than the advertised 0.75" on the cone, but the M12 thread fit. It's a "thin" diameter, but the M12 thread is too small and won't fit (Thread only 1/2 turn.) Time to try another brand!
