American Type Hose Clamp
American type hose clamps are perforated worm-drive clamps used for hose and pipe fastening in automotive, agricultural machinery, industrial equipment, and general piping applications. The perforated band allows a flexible adjustment range, while the worm-drive structure supports regular tightening for repair, assembly, and general fastening work.
Yueding supplies American type hose clamps with regular reference sizes based on SAE size numbers and clamping ranges. 8.0 mm and 12.7 mm band width options are available, with common clamping ranges from 10–16 mm up to 228–254 mm, depending on the selected specification. For bulk orders, mixed sizes, or customer packaging requirements, we can help confirm the reference number, clamping range, band width, material grade, screw type, surface finish, and packing details before production.

Automated Production and Size Control
Our American type hose clamps are produced on fully automated production lines. Unlike some large-diameter German type hose clamps that may still require manual support, the standard-size American hose clamps we supply are manufactured through an integrated process, including band perforation, housing riveting, band forming, and screw assembly.
Band tolerance can be controlled within ±0.02 mm, helping maintain more consistent appearance, dimensions, and assembly performance across long-term supply. This can help you reduce customer complaints, installation feedback, and repeated confirmation caused by batch-to-batch variation.
American type worm-drive clamps have a mature structure and a wide application range. With an overall automated hose clamp output of up to 1–1.2 million pieces per day, we can better support large-volume orders while maintaining cost-efficient production. For bulk purchasing projects, this helps you control sourcing costs and end-market pricing while still meeting regular fastening performance requirements.
Bulk Order, Packaging, and Specification Support
American type hose clamps are suitable for bulk orders where flexible size coverage and easy specification management are important. The perforated band allows a wider adjustment range, helping one specification fit different hose outside diameters within its clamping range.
For mixed-size purchasing or repeat orders, we can help confirm the common size range, band width, material, surface finish, and packing method before production. This makes it easier for you to manage regular stock items, repair kits, project supply, or distribution orders.
Packaging and specification identification can also be arranged according to your order needs. Bulk packing, poly bags, boxes, labels, barcodes, and kit combinations are available for easier sorting, warehousing, and repeat purchasing.
Related American-Style Hose Clamp Options
Quick Release Type
Designed for hose connections that need frequent opening, maintenance, or replacement. Quick-release structures and handle versions can be selected according to your operation needs.
With Positioning Holes
The pre-set positioning holes help reduce manual alignment errors during assembly. This type is suitable for applications that require more consistent positioning.
Heavy-Duty Type
The reinforced worm-drive structure with spring support provides stronger tightening performance than regular American-style hose clamps. It is suitable for heavier-duty fastening applications.
Black-Coated Type
Available with Dacromet black coating or electrophoretic black finish. The black surface helps with product identification and provides added corrosion resistance.
Factory Production and Bulk Order Support
American type hose clamps are regular production items in our hose clamp workshop. Depending on the size, order quantity, and product structure, production can be arranged through manual, semi-automatic, or automatic processes for different specifications and order needs.
For regular American type hose clamps, common production steps include band feeding, cutting, perforation, forming, housing assembly, screw matching, and packing preparation. Semi-automatic lines are often used for band forming, rolling, and related process support, while automatic equipment can be arranged for selected regular specifications.
During production, basic checks can be made on band width, perforation condition, forming shape, housing assembly, screw rotation, and surface appearance. If obvious defects are found, the affected pieces can be separated before packing and rechecked after adjustment or replacement.
For larger sizes, the clamp band can be rolled before packing when required, helping reduce packing volume for shipment. For mixed-size orders, different specifications can be packed or marked separately according to your confirmed packing plan, making it easier for you to sort, store, and manage repeat orders after arrival.
Product Questions & Answers
Will the perforated structure of American-style hose clamps damage the hose?
American-style hose clamps use a perforated steel band that meshes with a worm drive to achieve tightening. This structure can create localized pressure on the hose under high torque conditions. If the stamping process is not precise enough, burrs at the hole edges may gradually wear the hose surface during long-term use, and even cause slow leakage.
What is the difference between quick release and standard American-style hose clamps?
Why do American-style hose clamps loosen in vibration environments? How can it be improved?
What is the difference between rated torque and failure torque?
