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.

Too often I needed small screws and didn’t have the correct size.

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.

I got this for my electronics projects which use various sizes of screws (I also got the 2-56, 6-32, and the 8-32 size assortments) These have the nuts and screws in the specified sizes, but no washers, so I had to both flat and star washers separately - that's why I rated it four stars.
