Bought these at the same time as the White Knight 1306-1S-20AM which I thought were the same items in a different quantity but turned out to be slightly different - like two items used for the same and were made the same. Specifications, but from different manufacturers. They are slightly darker than those sold in packs of 20 and the embossing on the side of the nut is on the mating surface of the bushing rather than the bulge on the rim of the cone. The bulge also looks a bit narrower than in the 20-piece set.
