Clamps have a slotted screw. Tighten with a slotted screwdriver, hex nut driver, or a wrench.

A raised safety collar around the head of the screw prevents your screwdriver from slipping and damaging the hose or tube.

Here's everything you need to make your own 3" diameter and larger custom-length worm-drive clamps.

These clamps are easier to install than worm-drive clamps—crimp the pinch points with pinch-clamp pincers for a secure hold. They are also known as ear clamps.

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.

Clamps offer extra holding power in high-torque applications.

Not as bulky as our other constant-tension clamps, these round-wire clamps easily fit in cramped spaces. Use in low-pressure applications.

The T-bolt design provides excellent strength and creates a 360° seal. Clamps have a spring that automatically adjusts the clamp diameter when temperatures fluctuate.

These clamps are easier to install than our Extra-Strength Low-Profile Band Clamps. Also known as center-punch clamps, they seal with a quick hammer blow to the buckle.

Clamps have a slotted hex-head screw that flips up to release the band for quick opening.

Clamps have a smooth band with rolled edges to prevent them from cutting into your hose or tube.

An extended tail acts as a liner to protect soft hose and tube from being cut by the slots in the band.

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

Remove the bolt and flip open the hinged bridge to install.
