Natalie ★★★★★

I’ve been hunting for non-magnetic fasteners for a while, and these 18/8 stainless screws finally fit the bill—they don’t cling to my magnetic driver bit at all. The slotted fillister head seats nicely in tight spots, and at 600 per pack, I won’t run out anytime soon for projects around the shop.

I was rebuilding an old outdoor lamp and needed stainless steel screws that wouldn't rust—these are non-magnetic and definitely feel solid. The fillister head sits flush and the slotted driver caught perfectly on my screwdriver.

Stella ★★★★★

Perfect fit for a small robotics bracket I’m building — the #4-40 threads engaged cleanly without binding, and the slotted drive lets me torque them precisely with a jeweler’s screwdriver. These 18/8 stainless screws feel solid and corrosion-proof for outdoor use.
