Adam O. ★★★★★

The zinc plating on these little screws is holding up perfectly in my outdoor repair project. They fit snug into the hex washer head and distribute pressure just like I needed.

Ellie B. ★★★★★

Finally, a hex washer head that sits flush without slipping off the screwdriver. The zinc plating looks like it will hold up well against moisture, too.

Steven ★★★★★

The hex washer head really saved me time since I didn't need separate washers for my metal shelving project. They held tight without stripping, and the zinc finish looks clean and resists rust.
