DIN 557 is a German industrial standard that specifies the dimensions and requirements for square nuts. These nuts have a square geometry and internal thread and are typically used where high stability and load carrying capacity are required.DIN 557 square nuts are characterized by chamfered edges to facilitate mounting and dismounting.

Carbon Steel: Typically used for general applications. Stainless Steel: For environments where corrosion resistance is required. Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

HIGH LOADBEARING CAPACITY: Square nuts provide high preload and load carrying capacity due to their large contact area. Ease of Installation: Chamfered edges make the nuts easier to install and remove. Compatibility: Can be used with standard bolts for a variety of industrial applications.

Scope of Application

MACHINERY AND STRUCTURAL ASSEMBLY: Used in machinery and structural assembly to provide stable and reliable fastening. Heavy Machinery: In heavy machinery, these nuts can withstand high loads and pressures. Construction and engineering: Used in construction and engineering structures to ensure the stability and security of connections.
