Washer M14 A2 stainless steel DIN125A 15x28x2,5 mm

The ring is intended for bolts and threaded rods of M14. By distributing the force of the nut over a larger surface, you prevent the nut or bolt head from sinking into the material or damaging the surface. This is especially useful with softer materials, such as wood or aluminum, and with holes that are larger than the bolt.

For which applications is a M14 stainless steel washer suitable?

A flat washer made of A2 stainless steel is widely used in structures, machinery and installations where fasteners must resist moisture. Think of outdoor work, steel construction, fencing and maintenance of equipment. A2 stainless steel is a good choice if you want to limit corrosion. For extremely aggressive environments, such as seawater or chlorine-containing areas, a higher grade is often chosen. So always check whether A2 suits your situation.

Size and standard: how to choose the right washer

The size designation M14 refers to the thread of the bolt, not to the outer diameter of the washer. The inner diameter of 15 mm therefore leaves just enough room for the shank. Also check the outer diameter and the thickness of 2.5 mm, so that the washer fits within the available space and provides sufficient bearing surface. The DIN 125 A standard describes flat washers with these standard proportions.

Combining with bolts and nuts of the same material

Preferably use bolts, nuts and washers made of the same material. This prevents different metals from corroding each other and keeps the assembly equally resistant to weather.
