Shimano flanged LOW PROFILE axle nuts - brand new, never mounted. They are old stock, but it's probably from this century so I won't call them NOS.
SOLD IN SEALED BAGS OF 10 (if you open the bag, they cannot be returned)
The "height" of this nut is 9mm. This is a great choice for short axles or if you want to add thick washers.
Threading: 3/8" X 24T (fits most rear Skyway mags (coaster or freewheel) and most Coaster brake 3/8" rear wheels)
