SQUARE NUT
SQUARE NUT DIN-557
📌 Overview
The Stainless Steel Square Nut DIN 557 is a four-sided nut designed to provide greater surface contact with the mating material, improving resistance to loosening and enhancing torque distribution. Square nuts are ideal for structural assemblies, channel fittings, and applications where a wrench grip is required on multiple sides.
Manufactured from SS304 (A2) and SS316 (A4) stainless steel, these nuts offer excellent strength, corrosion resistance, and durability, making them suitable for construction, machinery, automotive, electrical, and marine applications.
