Olivia ★★★★★

I needed a bunch of #5-40 nuts for a project and these stainless ones held up perfectly, no stripping even with a power driver. The hex head gives a good solid grip from any angle.

Joseph P. ★★★★★

The hex heads on these #5-40 nuts grip a wrench perfectly, no slipping even when I’m cinching down panels in tight spots. The 18-8 stainless finish looks clean and I didn’t find a single burr across the whole 200-count bag. For the price per piece, this is a solid stash for any metalworking project.

Stella ★★★★★

Perfectly consistent threading on every single nut in this pack—no stripped or misaligned ones. The 18-8 stainless steel feels sturdy and corrosion-resistant, just what I needed for an outdoor panel project.
