A thumb screw instead of a slotted screw allows you to install these clamps without any tools.

Unlike vibration-resistant pinch clamps, these have a torque rating for extra holding power in high-vibration applications. They are also known as high-torque clamps.

Made of our most corrosion resistant stainless steel, these worm-drive clamps stand up to harsh acids and chemicals. Their band is smooth and has rolled edges, so they won’t cut into your hose or tube.

To prevent removal, these clamps can only be loosened with a special bit or screwdriver.

Clamps come packed in a box with individual compartments for each clamp size. To make sure they won’t cut into hose and tube, they have a smooth band with rolled edges.

Create 2" diameter and larger smooth-band worm-drive clamps.

Don't worry about your hose and tube expanding and contracting when temperatures fluctuate—these clamps have a Bellville spring that automatically increases and decreases the clamp's diameter.
