Victoria ★★★★★

I grabbed these to finish a small electronics project and the acorn heads give everything a much cleaner look than standard hex nuts. They threaded smoothly onto the bolts without any binding. Very happy with the polished stainless finish.

Aurora W. ★★★★★

Finally, a set of #4-40 cap nuts that actually feel solid; the 18/8 stainless steel gives them a nice weight and they threaded on smoothly without any binding.

Owen ★★★★★

These little acorn caps are perfect for giving a project a clean, finished look. The 18/8 stainless steel feels solid and they threaded on smoothly without any binding. I’m glad I bought the 100-pack since they’re so easy to misplace.
