304 stainless steel worm drive hose clamps use a perforated metal band, formed housing and adjustable screw to secure flexible hose or tubing around a fitting. AODSON supplies clamp ranges for industrial equipment, automotive systems, ventilation, water lines and OEM assemblies, with material, diameter range and testing defined by the order specification.
Product Overview
A worm drive hose clamp tightens as the screw engages the slots in the stainless steel band. Turning the screw draws the band through the housing, reducing the clamp diameter and applying circumferential pressure around the hose. The design offers a broad adjustment range and can be installed or removed with common tools.
The pictured products have perforated bands and visible 304 markings. The marking should not be used to assume that every clamp component has the same grade; the band, housing and screw materials must be confirmed in the purchase specification when an all-stainless assembly is required.

Key Features
- Adjustable diameter: one clamp size covers a defined range of hose outside diameters.
- Reusable screw mechanism: the clamp can be loosened and retightened during service when the application permits reuse.
- Corrosion-resistant options: 304 and 316 stainless configurations can be selected for outdoor, washdown or marine-related environments.
- Perforated band engagement: formed slots provide positive engagement with the worm screw.
- Range-based supply: coordinated sizes, markings and packaging can support distributors and OEM assembly lines.
304 vs 316 Stainless Steel Hose Clamps
Grade 304 is widely used for general industrial, automotive, water and outdoor applications. Grade 316 provides improved resistance in chloride-rich, coastal, marine and some chemical environments. The correct grade depends on exposure, temperature, cleaning chemicals, service life and the consequence of clamp failure.
Buyers should specify whether only the band is stainless or whether the band, housing and screw must all use a stated stainless grade. Mixed-material clamps may look similar but behave differently in corrosive service.
Band, Housing and Screw Design
Clamp performance depends on more than nominal diameter. Band width and thickness influence load distribution, while slot geometry affects screw engagement. The housing must retain the screw and guide the band without excessive deformation. Screw thread, drive geometry and bearing surfaces affect installation torque and repeatability.
For soft hose, the clamp should distribute pressure without cutting or extruding the hose through the band slots. For reinforced or thicker hose, the required installation load and joint geometry may be different. A hose clamp should be selected as part of the complete hose, fitting and operating-pressure system.
Manufacturing Process
Production can include stainless strip slitting, edge control, slot punching, band forming, housing stamping and forming, screw manufacture, assembly, marking and cleaning. Passivation may be specified for stainless components after forming and assembly.
Tooling and process controls are selected according to band dimensions, slot pattern, annual quantity and required consistency. Burr control is important because rough band edges or slots can damage hose surfaces and complicate assembly.
Typical Applications
- Automotive coolant, intake and general hose connections
- Industrial pumps, filters and process equipment
- Water, irrigation and plumbing assemblies
- Ventilation, ducting and dust-collection systems
- Marine, outdoor and washdown equipment using an approved material grade
- Agricultural machinery and general OEM equipment
Standards and Performance Requirements
Worm drive clamps may be specified to customer drawings or applicable requirements such as DIN 3017 or SAE J1508. The photographed clamps should not be assumed to comply with a particular standard solely from appearance. Standard edition, dimensional series, material combination, torque and test requirements must be stated in the RFQ.
Pressure capability belongs to the complete hose connection rather than the clamp alone. Hose material, fitting geometry, temperature, vibration, installation torque and clamp position all influence sealing performance.
Quality Control
Inspection can cover material identification, band width and thickness, slot dimensions, free diameter, adjustment range, housing geometry, screw engagement, edge condition and marking. Project-specific testing may include installation torque, free-running torque, destructive torque, pull-off, corrosion or pressure testing when the method and acceptance criteria are supplied.
RFQ Information
For a practical quotation, provide the hose outside diameter or required clamp range, band width, material combination, annual quantity and service environment. If the clamp is part of a pressure or safety-critical connection, include the complete assembly requirements and test standard.

Frequently Asked Questions
Are all parts of the pictured clamp made from 304 stainless steel?
The band carries a visible 304 marking, but photographs cannot verify the housing and screw grades. Specify the material of each component when an all-304 or all-316 assembly is required.
Can AODSON supply 316 stainless steel hose clamps?
Yes. Grade 316 configurations can be reviewed for coastal, marine and chloride exposure. The required grade should be stated separately for the band, housing and screw.
Do these clamps comply with DIN 3017 or SAE J1508?
They can be produced or sourced against a stated standard and test requirement. Compliance is confirmed only after the dimensional series, material combination and acceptance tests have been reviewed.
What size information is needed?
Provide the minimum and maximum hose outside diameter, band width, installation space and required adjustment range. Application temperature, pressure, vibration and corrosion conditions should also be included.
