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.

Metric Brass Flanged Knurled-Head Thumb Nuts

Made from zinc-plated brass, 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.

Brass Wing Nuts

These wing nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The wings provide more leverage for greater torque while tightening than knurled-head thumb nuts.
