Easy to use, strong, and versatile, these hose clamps are the most common. Tighten their slotted screw with a screwdriver, hex nut driver, or 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.

Installing these clamps is a snap—push their interlocking teeth together with your fingers, then squeeze tight with pliers. To remove, use pliers to push sideways and separate the teeth.

These clamps have a wider band than other constant-tension clamps, which provides more coverage and reduces the chance of leaks.
