Reinforced Plastic Knurled-Head Thumb Nuts

An aluminum insert with strong threads withstands more torque during installation. They're chemical resistant, nonconductive, and lightweight. The head is knurled for slip-resistant controlled adjustment and the collar raises the head to make it easy to grip.

Low-Profile Thumb Nuts

Use these thumb nuts in low-clearance applications or jam one against another nut to hold it in place. The knurls provide a slip-resistant grip for controlled adjustment. A black-oxide finish provides mild corrosion resistance in dry environments.

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.

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.
