SQUARE NUT DIN 557 12MM A4

Quantity:

A square nut is a four-sided nut that provides a large bearing surface for better resistance to loosening and improved tool grip. The square shape allows for easier tightening with a wrench and reduces the risk of rounding off corners compared to hex nuts. It’s often paired with flat washers to prevent damage to the work surface and ensure even load distribution.
