Flat Square Nuts (DIN 562)

FULLERKREG DIN 562 thin pattern square nuts are manufactured to the Deutsches Institut für Normung standard across multiple materials and surface finishes. Their four-sided geometry delivers a larger bearing surface than hexagonal nuts, enabling higher clamping torque and superior resistance to loosening. The reduced thickness compared to DIN 557 makes them ideal for space-constrained assemblies in electronics, sheet metal, furniture, marine, and structural applications. Available in metric sizes M2 through M10.

Standard Reference

DIN 562 specifies thin pattern square nuts with metric threads. Issued by the Deutsches Institut für Normung (DIN), the standard remains widely used in Germany, Europe, and globally. DIN 562 nuts are thinner than DIN 557 counterparts, providing the advantage of fitting tighter spaces while maintaining a four-sided bearing surface for anti-rotation and higher torque capacity. FULLERKREG manufactures all DIN 562 variants in strict conformance with dimensional tolerances.
