USA Made Extra Tall Cap Nuts with a Flat Top and Deeper Internal Threading

Extra Tall Flat Cap Nuts (also called Extra Tall Flat Acorn Nuts, Top Hat Nuts, or Flat Extra Tall Cap Nuts) are cap nuts with a deeper internal threading and a flat cap. They are similar to acorn nuts or cap nuts, but the top of the nut is not domed.

Extra Tall Flat Cap Nuts are available in 18-8 Stainless Steel, which is the industry standard for corrosion and rust resistance (particularly in applications exposed to fresh water moisture).


All Extra Tall Cap Nuts from Albany County Fasteners are proudly Made in the USA.
