Square Nut Class 5 Steel Zinc DIN 557

This configuration is not available. Make another selection.

Full height, four-sided square nuts provide greater surface contact (compared with a standard 6-sided hex nut) against the part being fastened. This provides greater resistance to loosening. Square nuts work well in blind spots because they can be tightened with pliers or a wrench.

Zinc Plated finishes provide corrosion resistance without sacrificing strength.
