A screw hose clamp, commonly called a worm-drive clamp, is a versatile and adjustable fastening device used to secure hoses onto fittings. It consists of three main components: a perforated stainless steel band, a threaded screw mechanism, and a slotted screw head.

The clamp works by tightening the screw, which pulls the band uniformly around the hose, creating a secure, leak-proof seal. Its adjustable design accommodates various hose diameters, while the stainless steel construction ensures durability and corrosion resistance in demanding environments.

Widely used in automotive, plumbing, and industrial applications, screw hose clamps offer easy installation, reusability, and reliable performance. They are ideal for coolant systems, fuel lines, and hydraulic connections, providing strong clamping force without damaging the hose when properly installed.

Various types of hose clamp screws

The term stainless steel screws typically refers to steel screws with the ability to resist corrosion from air, water, acids, alkalis, salt, or other corrosive mediums. Stainless steel screws are generally corrosion-resistant, durable, and find applications in environmental protection equipment, medical devices, communication equipment, and other fields.depending on the alloy composition, emphasis may vary between stainless properties and acid resistance. Some steels, while corrosion-resistant, might not necessarily be acid-resistant. Acid-resistant steels typically also possess stainless properties. In people's daily lives, the commonly referred to stainless steel is often austenitic stainless steel.The stainless steel fasteners we use primarily employ austenitic grades such as 302, 304, 316, and the "low-nickel" 201, depending on the specific requirements.

How to Use a Screw Hose Clamp?

Select the Right Size: Choose a clamp slightly smaller than the hose diameter when fully open to ensure a tight fit.
Position the Clamp: Slide the clamp over the hose end before attaching it to the fitting. Ensure the screw head faces outward for easy access.
Connect the Hose: Push the hose firmly onto the pipe or barbed fitting until it seats completely.
Tighten the Clamp: Center the clamp over the connection, then use a screwdriver to turn the screw clockwise. Tighten until the hose is snug but avoid over-tightening, which can damage the hose.
Check for Leaks: Test the system under pressure and adjust if necessary.

Characteristics of Screw Hose Clamps

Screw hose clamps, also known as worm-drive clamps, feature a stainless steel band with evenly spaced grooves and a threaded screw mechanism for adjustable tightening. Their key advantage is 360-degree uniform pressure distribution, ensuring leak-proof seals on hoses of various diameters.

The corrosion-resistant stainless steel construction makes them durable in wet, high-temperature, or chemical-exposed environments. The slotted screw head allows easy adjustment with standard screwdrivers, offering convenient installation and maintenance. Unlike fixed clamps, their adjustable tension accommodates hose compression over time.

These clamps provide strong clamping force while preventing hose damage when properly tightened. Their simple, reusable design works across automotive, industrial, and household applications, balancing reliability with cost-effectiveness.
