Metric 18-8 Stainless Steel Flanged
Knurled-Head Thumb Nuts
Made from 18-8 stainless steel, these thumb nuts have good chemical resistance and may be mildly magnetic. The flange distributes the load over a large area and reduces stress where the nut meets the material surface. A knurled head provides a slip-resistant grip for controlled adjustment.
Passivated stainless steel nuts provide added protection against oxidation and corrosion.

Sanitary Spade-Head Thumb Nuts
Cover and protect threads in sanitary environments, such as food-processing or pharmaceutical plants. These thumb nuts are easily adjusted by hand, so there’s no need for tools that could contaminate or scratch equipment. Made of 316 stainless steel, they resist corrosion from frequent washdowns with harsh cleaners. They have extremely smooth surfaces, rounded edges, and no horizontal ledges—all of which help prevent bacteria from growing.
Standard thumb nuts are easier to grip than narrow thumb nuts, so they give you greater leverage for turning.
Narrow thumb nuts have a slim profile to fit into tight spaces.
