## Customer Reviews

### ⭐⭐⭐⭐⭐ If your a Maker, you need these
*by K***K on July 7, 2024*

Exactly what I needed....I'm a Maker with Arduino boards and Boxes that I 3D Print. I need to mount the boards in the boxes for a finished product.I'm guessing you do to.These are good.

### ⭐⭐⭐⭐⭐ Good sizes for electrical work.
*by J***E on April 6, 2024*

I purchased these bolts/screws to work on installing plugs and switches. Many times the bolts/screws used on plugs and switches are too short or are lost. These are perfect replacements. I also purchased a kit with longer bolts/screws. Excellent assortment.

### ⭐⭐⭐⭐⭐ More Value Than Expected
*by R***T on September 26, 2023*

Not only do you get a bazillion 4-40 screws in all lengths, but it’s all squeezed into a small convenient box labeled with the lengths in each compartment. My only gripe is the nuts are packaged separately in a small bag, really no big deal. Definitely worth the money.
