Hex-Head Thumb Nuts

Tighten these thumb nuts with a wrench for more torque while fastening. They have a flange that distributes the load over a large area and reduces stress where the nut meets the material surface. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

Brass Flanged Knurled-Head Thumb Nuts

These thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. 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.

Zinc-plated brass nuts are more corrosion resistant than plain brass nuts.
