Non-Serrated Metric Hex Flange Nuts in Class 10.9 Steel (also known as Smooth Flange Nuts, Washer Face Nuts, or Free-Spinning Flange Nuts) feature an integrated smooth washer flange at the base of the nut. Unlike serrated flange nuts, the non-serrated design allows the nut to spin freely during installation and removal without scratching or marring the mating surface, ideal for painted, coated, or finished materials. The wider flange distributes clamping force over a larger area, reducing the risk of pull-through on softer materials and eliminating the need for a separate flat washer. These metric flange nuts are manufactured from high-strength Class 10.9 alloy steel with a zinc plated finish for corrosion resistance. Class 10.9 offers approximately 25% greater tensile strength than Class 8.8, making these nuts the preferred choice for heavy-duty automotive, structural, machinery, and high-stress fastening applications where maximum clamping force is required.
