Great value, minor case issue

The screws and nuts are top-notch 304 steel. My only complaint is that the plastic divider in the box was slightly cracked upon arrival, but the hardware itself is perfect.

Professional quality

As a contractor, I go through fasteners quickly. This kit offers professional-grade quality at a reasonable price. The Phillips heads don't strip easily.

Good variety of sizes

The range of sizes covers most of my needs. I wish there were slightly more of the medium-sized screws, but overall it's a solid purchase.

No rust after months outside

I used these for a garden trellis project exposed to rain. After three months, there is absolutely no sign of rust. The flat heads sit flush as expected.
