A Square Nut DIN 557 is a four-sided internally threaded fastener designed to provide greater surface contact and superior grip compared to standard hex nuts. Its square shape resists rotation effectively and allows easy positioning using simple tools, making it ideal for structural and assembly applications.

Square nuts are commonly used in woodworking, construction, and heavy mechanical assemblies, especially where precise alignment and high load-bearing capacity are required.

Available Sizes:

Metric: M3 to M16
