Customer Reviews (4.8 / 5 · 5 reviews)

Miles ★★★★★

The finish on these cap nuts is smoother and more uniform than I expected. They look clean and professional on the exposed bolts of my project, and the acorn head gives it a finished appearance. Definitely worth the price for the quantity you get.

Timothy I. ★★★★★

I put a few of these on some exposed bolts on a trailer hitch, and the acorn heads give it a clean, finished look. The threads caught easily and they snugged down tight without any binding.

Charlotte ★★★★★

The nickel plating on these acorn nuts is genuinely smooth and even, no flaking or rough edges when I ran my finger across them. They snugged down tight on my bolts with a clean, finished look that beats exposed threads any day. Sixty in the pack means I've got plenty left for future projects.
