Elizabeth ★★★★★

Installed these on a marine hatch that’s constantly exposed to salt spray, and the 316 stainless steel shows zero signs of corrosion after a month. The hex head gave a solid grip with my socket driver. Exactly what I needed for a damp environment.

Scarlett ★★★★★

These bolts tightened down perfectly on a saltwater tank stand I was building—the 316 stainless seems like it will hold up to the moisture without any rust worries.

Daniel ★★★★★

Took a whole box down to the workbench to assemble a batch of brackets, and every single one of these M4s threaded in clean with no duds, which is rare for a 400-count pack. The 316 stainless finish gives me peace of mind for the outdoor bits that’ll see moisture. Removed about ten without stripping
