Miles X. ★★★★★

The slot on these screws holds a standard flathead driver perfectly without slipping, which I really appreciate. Very happy to have a full pack of these 18/8 stainless bolts for future outdoor projects.

Penelope O. ★★★★★

Used three of these to replace corroded screws on an outdoor gate hinge, and the 18/8 stainless is holding up perfectly after a week of rain. The slotted head grabbed nicely with a standard flathead, no stripping even when I cinched them down tight.

Timothy ★★★★★

These are solidly built for the price, the 18/8 stainless steel is definitely non-magnetic as described, which was important for my electronics enclosure. The slotted heads fit my screwdriver snugly, and the threading was clean enough to start by hand. Took a bit of effort to drive them fully in wit
