A4 Stainless Thin Square Nut DIN 562

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. The reduced height profile of thin square nuts makes them perfect for low clearance, tight space applications.

Material: A4 Stainless


A4 / 316 Stainless Steel square nuts are "marine grade" corrosion resistant; suitable for salt water applications. A4 fasteners also offer increased resistance to chemicals when compared with A2 stainless fasteners.


Commonly used in wet environments. Popular across a wide range of industries: automotive, agriculture, photographic, medical / surgical, food processing, robotics, architectural detailing, construction, HVAC, healthcare, sanitary, transportation, clean energy, etc
