British Type Worm Gear Hose Clamp Production
British Type Worm Gear Hose Clamp Details
British Type Worm Gear Hose Clamp Batch

While stainless steel offers maximum corrosion resistance, our zinc-plated carbon steel alternative provides 95% of the anti-rust performance at nearly 60% of the cost. It is the smart economic choice for applications requiring frequent disassembly for maintenance, as the galvanized layer offers just enough protection without galling threads.

This British Standard (BS) worm gear hose clamp is manufactured from high-grade galvanized iron (Zinc-plated carbon steel). Unlike standard stainless variants, our galvanized model offers a unique balance of moderate torsional strength and cost-efficiency, making it the preferred fastener for medium-to-heavy-duty connections. The distinctive hexagon slotted nut design allows for rapid screwdriver or socket wrench adjustment, ensuring a secure, vibration-proof grip on soft hoses and rigid pipes.

Wide Adjustability with Aesthetic Finish

The fully galvanized surface provides a uniform, bright appearance. When connecting soft and hard pipes above 30mm, the worm drive ensures an even circumferential load, resulting in a clean, leak-proof assembly.

Superior Torsional Performance

Engineered to withstand high vibration environments. The robust interlocked housing prevents band separation under extreme pressure, making it safer than ordinary stamped clamps.

Versatile Compatibility

The friction-optimized worm gear lowers operational resistance, allowing for precise torque control without damaging the hose surface.

Parts band, housing and screw Material w1: all parts are galvanized steel
This clamp is not limited to automobiles. Its robust design makes it an ideal fastening solution for:
  • Mobile Machinery: Tractors, forklifts, and locomotive cooling systems.
  • Marine & Offshore: Shipboard piping for water and oil lines (corrosion-resistant coating).
  • Industrial Infrastructure: Petroleum, chemical, and pharmaceutical plants where dust-proof seals are critical.
  • Agricultural Irrigation: Connecting PVC and rubber hoses in high-pressure water delivery systems.

We support OEM orders. Whether you require specific slot punching, non-standard diameters, or private labeling, our engineering team can adapt the tooling accordingly. With bulk inventory ready for 20ft/40ft containers, we ensure fast turnaround for global B2B partners.

We understand that safe delivery is just as critical as product quality. All our British Type galvanized hose clamps are packed in standard export kraft cartons as the default option. For branding purposes, we also offer customized printed cartons—available in white, black, or full-color printing—to reinforce your brand identity on every shipment.

To ensure your order arrives in perfect condition, each carton is securely taped and, if necessary, reinforced with woven bags for extra protection against moisture and tearing. Finally, all cartons are strapped onto pallets—you can choose between sturdy wooden pallets or durable iron pallets, depending on your handling and storage preferences.

We also offer flexible packaging solutions for mixed sizes, small trial orders, or large-volume container loads. Just let us know your requirements, and we will tailor the packaging accordingly.

Frequently Asked Questions

What range of clamping sizes do you produce for these hose clamps?
Our manufacturing line covers clamping diameters from 8mm to 200mm (with standard sizes ranging up to 210mm). We provide band width and thickness options of 9.7mm x 0.8mm for smaller sizes and 11.7mm x 0.9mm for heavy-duty applications.
What materials are used in the construction of these clamps?
These British Type worm gear hose clamps are made under the W1 specification, meaning all components (the band, housing, and screw) are constructed from high-grade galvanized carbon steel (Zn-plated) for cost-effective corrosion resistance.
How does the corrosion resistance of zinc-plated steel compare to stainless steel?
Our zinc-plated carbon steel clamps offer approximately 95% of the anti-rust performance of stainless steel under typical conditions but at nearly 60% of the cost. They pass a 72-hour salt spray test, making them an excellent choice for budget-conscious projects requiring frequent maintenance disassembly.
Can these clamps be adjusted with standard tools?
Yes, our clamps feature a hexagon slotted nut design. This allows rapid and convenient adjustments using either a flat-head screwdriver or standard socket wrenches, ensuring a reliable, vibration-proof fit.
What custom OEM and packaging options do you provide?
We support OEM requests including custom diameters, specific slot punching, and private labeling. For packaging, we offer customized printed cartons in white, black, or full-color, reinforced with woven bags and strapped onto your choice of wooden or iron pallets.
