18-8 Stainless Steel Flanged Knurled-Head Thumb Nuts
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.
