Materials & strength

Thin square form

The low, four-sided profile locates in pressings and channels and keeps the fastener stack shallow in sheet-metal assemblies.

Zinc plated steel & stainless A2/A4

Zinc plated grade 4 covers general indoor work; A2 and A4 stainless cover corrosive environments, with A4 preferred for chloride or marine exposure.

Frequently asked

What is a DIN 562 square nut?

DIN 562 covers thin square nuts in the smaller metric sizes. The flat, four-sided form suits sheet-metal work and light fabrications where a low-profile captive nut is wanted.

Where are thin square nuts used?

Typically behind sheet metal, in electrical enclosures and in pressings or channels that hold the nut against rotation, so the screw can be fitted and tightened from the front. The thin profile keeps weight and stack height down.

What is the difference between DIN 562 and DIN 557?

DIN 562 is the thin square nut for smaller sizes, while DIN 557 is the standard-height pattern. If a drawing specifies one, the height difference usually matters to the assembly, so match the designation.

What materials are DIN 562 nuts available in?

DIN 562 square nuts are available in zinc plated steel grade 4 and stainless steel A2 and A4 across a wide range of metric sizes. Stainless suits damp or corrosive conditions.
