DIN557 M5 Square Nuts

Crafted from high-quality stainless steel, this square nut features a domed shape with a hexagonal base, making it easy to tighten and secure.

The SS304 DIN557 M5 Square Nuts are small but strong metal fasteners, perfect for connecting parts securely in a wide range of applications. Made from high-quality 304 stainless steel, these nuts are highly resistant to rust and corrosion, making them suitable for both indoor and outdoor use.
With an M5 coarse thread, they’re easy to screw onto matching bolts or threaded rods, and they hold tightly in place. Their square shape provides more surface contact than regular hex nuts, which helps prevent slipping or loosening — especially useful in areas with vibration or movement.
These nuts meet the DIN557 standard and have a natural metal finish. With a strength rating of 700PA, they offer solid performance for everyday mechanical, construction, or DIY projects.
If you're looking for a reliable, rust-resistant nut for secure fastening, the SS304 DIN557 M5 Square Nut is a simple and smart choice.
