The American hose clamp, more formally known as a screw clamp, worm-drive clamp or perforated band hose clamp, is a quintessential and widely recognized fastener used primarily to secure hoses onto fittings. Its design, durability, and practicality have made it an industry standard across numerous applications, from automotive and plumbing to industrial and marine systems.

The defining feature of the American style hose clamp is its simple yet robust construction. It consists of three main components: a perforated or slotted stainless steel band, a housing that contains a threaded worm gear, and a screw (the worm). When the screw is turned with a screwdriver, it engages the slots on the band, pulling it through the housing to tighten the loop uniformly around the hose. This worm-drive mechanism allows for precise adjustment, a strong, even seal, and reliable pressure distribution, preventing leaks under a wide range of temperatures and pressures.
