Jacob I. ★★★★★

Having a full 5000-count bag means I won't be scrambling for more mid-project—the hex shape makes them easy to grip with a wrench even when working in tight spaces. They seated perfectly on my #4-40 bolts without any wobble.

Hannah I. ★★★★★

For a small electronics project, I needed a solid batch of nuts and these #4-40 hex ones are exactly what I was looking for. The steel material feels strong and the hex head makes them easy to grip with a wrench.

Sophia O. ★★★★★

Half a day of small electronics work and I barely put a dent in the bag—these #4-40 steel hex nuts thread cleanly onto my bolts without any fuss. The count is genuinely generous for the price, and the hex heads give a solid grip for my pliers.
