Stainless Steel / Coarse Thread, Spin-Locking Flanged
The best of both worlds! Combine the protection of an acorn nut with a conical lock washer and you've got a Spin-Locking Acorn Nut.

These nuts turn freely during install until the conical washer is compressed against the mating surface as the nut is tightened. The locking tension created by the compressed washer helps prevent the nut from loosening during vibration. The washer also evenly distributes this force over a larger area against the fastening surface.

Reusable, a one-piece solution versus using a separate lock washer and a nut.

Stainless acorn nuts are for damp environments for corrosion resistance, popular across a wide range of industries: automotive, motorsport, industrial machinery, architectural finish work, agriculture, food processing, clean energy, etc.

Also known as dome nut, hexagon domed cap nut.
