What is worm drive clamp?
A worm drive clamp, also known as a worm gear hose clamp, is a versatile fastening device designed to securely attach hoses onto fittings such as pipes or tubes. It is constructed with a durable metal band featuring a screw thread pattern and a captive screw mechanism. When the screw is rotated, the worm gear engages with the band’s slots, causing the band to contract evenly around the hose. This uniform tightening action distributes pressure consistently, preventing leaks and ensuring a reliable connection without damaging the hose surface.
Key Features of Worm Drive Clamp
Versatile Applications
Worm drive clamps can be adjusted to fit a wide range of hose sizes and materials. Their flexibility allows one clamp type to serve multiple purposes with reliable performance.
Durable Materials
Made from stainless steel or carbon steel, worm drive clamps are built to last. Stainless steel options provide excellent corrosion resistance for long-term performance.
Easy Installation
Worm drive clamps are designed for quick and simple use. With just a screwdriver or socket tool, they can be tightened or loosened easily for fast setup and adjustments.
Vibration Resistant
The design applies even pressure around the hose, ensuring a firm seal. This prevents loosening caused by vibration and helps protect against leaks.
Heavy-Duty Material Selection: Stainless Steel & Metal Gear Clamps
We offer gear-type hose clamps made from a variety of high-strength metal materials to adapt to different working environments. Each material of the worm gear clamp has unique performance advantages to meet various application needs, from general pipe fastening and marine saltwater environments to ordinary industrial fluid pipelines.

Difference Between Hose Clamp Types
- Mechanical Structure：Its most distinctive feature is the perforated steel band. A row of square holes are punched through the strip. The threads of the adjusting screw lock into these holes to tighten or loosen the clamp.
- Tool Compatibility：The screw head is made to universal standards, so it works with most common tools. You can easily operate it using flat-head screwdrivers, cross-head screwdrivers or hex socket wrenches.
- Structural Performance：Excessively high torque may cause stress around the holes. This type is practical, versatile and cost-effective, ideal for general fastening applications.
- Inner Wall Design：The steel band has no holes at all. The inner surface is precision stamped to be fully flat and seamless, while the gear teeth are only embossed on the outer side.
- Hose Protection：Both edges of the band are rolled outwards to eliminate sharp metal edges. It will not scratch or cut soft hoses and provides reliable protection.
- Torque Resistance：The solid band together with a robust short screw housing delivers great stability. The clamp won’t bend or deform even under heavy torque.
- Thread Making Process：Instead of punching holes, the band is cold-rolled to form integrated threads. The original structure and full thickness of the steel are well preserved for consistent strength.
- Even Pressure Distribution：The screw housing is mounted right in the middle of the band. When adjusted, it creates balanced 360° clamping force all around the hose.
- Standard & Application：Manufactured in accordance with British standards like BS 5315, it features a heavy-duty build. It is mainly used for rigid, high-pressure industrial hose systems.
