Robert T. ★★★★★

Great for a project where I needed non-magnetic fasteners. The slotted drive is old-school but works perfectly with a flathead screwdriver, and the 18mm length was exactly what I needed.

Abigail V. ★★★★★

I was pleasantly surprised by how clean the flat head sits flush in softer woods once tightened. No stripping or bending, even driving them the full 18mm depth.

William ★★★★★

The 18/8 stainless steel is exactly what I wanted for outdoor hardware—no rust worries even after a few rainy weeks. Slotted heads seated cleanly with a standard driver, and the 900-count box means I won't need to reorder anytime soon.
