About Nuts, Materials, and Finishes

Metric 18-8 Stainless Steel Knurled-Head Thumb Nuts

Made from 18-8 stainless steel, these metric thumb nuts have good chemical resistance and may be mildly magnetic.

Reinforced Plastic Knurled-Head Thumb Nuts

These thumb nuts have an aluminum insert to withstand more torque than plastic thumb nuts during installation.

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

These metric thumb nuts have good chemical resistance. The flange distributes pressure over a large area to reduce stress on your part.

Metric Brass Flanged Knurled-Head Thumb Nuts

These metric thumb nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. The flange distributes pressure over a large area to reduce stress on your part.

Low-Profile Thumb Nuts

Use these thumb nuts in low-clearance applications or jam one against another nut to hold it in place.

Wing Nuts

Metric 18-8 Stainless Steel Wing Nuts

Made from 18-8 stainless steel, these metric nuts have good chemical resistance and may be mildly magnetic.

Metric Super-Corrosion-Resistant
316 Stainless Steel Wing Nuts

Made from 316 stainless steel, these metric wing nuts have excellent chemical resistance and can be used in saltwater environments.

Metric Steel and Iron Wing Nuts

These metric wing nuts provide more leverage for greater torque while tightening than knurled-head thumb nuts.

Metric Plastic Wing Nuts

Made from nylon 6/6, these metric wing nuts are chemical resistant, nonconductive, and lightweight.

Sanitary Spade-Head Thumb Nuts

Cover and protect threads in sanitary environments, such as food-processing or pharmaceutical plants.

Handles and Knobs

Threaded Through-Hole Knobs

Long shafts can thread through these knobs for mounting versatility. The knobs provide a secure grip to position, tighten, and hold fixtures, equipment, and machinery.

Handle Nuts

Use these handles for quick assembly and disassembly. Their offset grip provides leverage, making them a good alternative to wing nuts.
