Customer Reviews (4.4 / 5 · 5 reviews)

Ava ★★★★★

Needed some non-magnetic fasteners for an electronics enclosure, and these 18/8 stainless steel screws fit the bill perfectly. The slotted drive was easy to work with, and having 800 in a pack means I won't run out anytime soon.

Miles ★★★★★

Ordered these for a greenhouse shelving project, and the stainless steel holds up perfectly in the damp conditions without any rust. Each screw threads smoothly into pre-tapped holes, and the 800-count box means I have plenty left over for future repairs.

Ryan ★★★★★

Used a hundred of these to rebuild a washdown station at work — the 18/8 stainless held up perfectly against the spray. The slotted drive was a bit fiddly with a screwdriver, but these are solid and the corrosion resistance is exactly what I needed.
