SQUARE NUT
SQUARE NUT DIN-557
📌 Overview
The Stainless Steel Square Nut – DIN 557 is a precision-engineered fastening component designed for use with square head bolts, machine screws, threaded rods, and general fastening applications. Its four-sided square profile provides a larger contact surface than conventional hex nuts, offering improved resistance to loosening and making it easier to hold with standard tools in confined spaces.
DIN 557 specifies Product Grade C square nuts with ISO metric threads, making them suitable for general engineering, machinery, fabrication, construction, and industrial applications. These nuts are commonly available in M5 to M16 thread sizes.
Manufactured from Stainless Steel SS304 (A2) and SS316 (A4), DIN 557 Square Nuts provide excellent corrosion resistance, high durability, and long service life, making them ideal for indoor, outdoor, and marine environments.

THIN SQUARE NUT DIN-562
📌 Overview
The Stainless Steel Thin Square Nut – DIN 562 is a precision-engineered low-profile fastening component designed for applications where limited installation space, reduced nut height, and secure locking are required. Featuring a square profile with a thin body, it provides a larger contact area than conventional hex nuts while allowing easy tightening using standard spanners or pliers.
DIN 562 specifies thin square nuts with metric threads in Product Grade B, commonly available from M1.6 to M10. These nuts are ideal for electrical equipment, machinery, furniture, automation systems, sheet metal assemblies, and precision engineering applications where clearance is restricted.
Manufactured from Stainless Steel SS304 (A2) and SS316 (A4), DIN 562 square nuts provide excellent corrosion resistance, durability, and long service life, making them suitable for indoor, outdoor, and marine environments.
