18-8 Stainless Steel Thin Square Nut M8 x 1.25 mm Thread

Two-thirds the height of typical square nuts and made of 18-8 stainless steel, these metric nuts are designed for use in low-clearance applications in humid, damp, and washdown environments. They’re often called square jam nuts because they can be jammed together to hold each other in place. They’re easily gripped with a wrench due to their flat, broad sides, which also prevent them from rotating in channels and square holes. Compared to hex nuts, a greater area is in contact with the fastened surface. And compared to steel nuts, they’re slightly less strong.

DIN 562—These nuts meet DIN 562, an international standard that signifies their material and dimensions are compatible with other products and tools.
