FREQUENTLY ASKED QUESTIONS (FAQ)

What is the advantage of a square nut?
The square shape provides a larger contact surface and improved grip during assembly, which reduces the risk of rotation in certain applications.

What is DIN 557 used for?
DIN 557 is used for square nuts intended for mechanical and industrial fastenings where a square design is required.

Can the nut be used in marine environments?
Yes. A4 is acid-proof stainless steel with high resistance to saltwater, moisture, and corrosive environments.

What is the difference between A2 and A4?
A2 is primarily used in normal outdoor environments, while A4 is adapted for marine environments and applications with higher demands on corrosion resistance.

Can the square nut be used with stainless bolts?
Yes. For optimal corrosion resistance, use in combination with stainless screws or bolts of the corresponding material grade.
