Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

The 82° countersink sits perfectly flush in my aluminum panels, and the slotted drive gives just enough grip without stripping. Pack of 2000 means I won't be reordering anytime soon.

Alexander ★★★★★

I’ve been using these to assemble small electronics enclosures, and the 82° flat head sits perfectly flush every time. The 18/8 stainless steel feels solid and hasn’t shown any corrosion after a few weeks.

Daniel ★★★★★

Perfect fit for mounting these aluminum panels I've been working on. The 18/8 stainless steel finish is clean and uniform across all two thousand pieces. No stripped heads or burrs so far.
