Worm Drive Hose Clamp A worm drive hose clamp is a type of fastening device used to secure hoses onto fittings such as pipes, tubes, or spigots. It is one of the most commonly used hose clamps in plumbing, automotive, and industrial applications. Key Features: Design – Made of a circular metal band with a screw housing; tightening the screw causes the band to tighten around the hose. Mechanism – Operates using a “worm gear drive” system where the screw meshes with the slots on the clamp band. Material – Usually manufactured from stainless steel or galvanized steel for durability and corrosion resistance. Adjustability – Can fit a wide range of hose diameters due to its screw-tightening mechanism.
