Matthew O. ★★★★★

These tiny 20mm machine screws are perfect for my 3D printer projects where I need non-magnetic stainless steel. The slotted drive is old-school and a bit fiddly with a screwdriver, but the 800-count pack means I've got spares for years.

Robert ★★★★★

I needed corrosion-resistant fasteners for outdoor equipment, and these 18/8 stainless steel M3 screws are exactly what I was after. The cheese head gives a solid grip for slotted drivers, and the 20mm length fit perfectly through my plastic enclosures. Pack of 800 is great value for keeping spares

Eva O. ★★★★★

The slotted drive on these M3 screws is precise, so my screwdriver fits snugly without any cam-out. They are perfect for outdoor projects where rust would be a problem, and the 20mm length was exactly what my hinge needed. The whole package of 800 feels like a lifetime supply for my hardware bin.
