PLAIN WASHERS TYPE B – DIN 125B

DIN 125B Plain Washers (Type B) are precision-engineered flat washers with a larger outer diameter compared to Type A, designed to provide greater load distribution and prevent surface damage under bolted connections. Their extended surface coverage makes them ideal for applications requiring enhanced clamping force over softer materials or where oversized holes need coverage.

At National Fasteners, our DIN 125B washers are manufactured to strict dimensional tolerances, ensuring consistent performance and compatibility with standard bolts, screws, and studs. They are available in a variety of materials and surface finishes to suit diverse industrial, structural, and mechanical applications.
