A Single Bolt Hose Clamp hollow bolt clamp is a specialized type of high-performance clamping device, easily identified by its distinctive hollow or "hollowed-out" housing and single bolt tightening mechanism. It is renowned for its ability to generate extremely high clamping forces, making it a superior choice for demanding industrial, automotive, and marine applications.
Material of single bolt hose clamp
W1 - All parts carbon steel with zinc plated.
W2 - Band and bridge stainless steel 201 or 304, bolt, sleeve and shaft carbon steel with zinc/nickel plated
W4 - All parts SS301/304
W5 - All parts SS316
Key Features of hollow single bolt hose clamp
Hollow/Slotted Housing:
This is the defining feature. The housing that contains the tightening mechanism is not solid but has large openings or slots.
Primary Function: These slots allow for visual inspection of the worm gear and band engagement even after installation. This helps in verifying that the clamp is properly seated and engaged.
Secondary Benefit: The openings allow water, dust, and other debris to easily wash out, preventing clogging and corrosion of the internal mechanism. This is often referred to as a "self-draining" or "self-cleaning" feature.
Single Bolt (Worm Gear) Mechanism:
Unlike standard hose clamps with a small Phillips/slot screw, this clamp uses a single, robust hex bolt or hex head screw (e.g., 6mm or 7mm).
This design allows for the application of high torque using a socket wrench or a hex key, resulting in a much more powerful and uniform clamping force compared to clamps with smaller screws.
FAQ of Single Bolt Hose Clamp
Q: What is the main advantage of a single bolt clamp over a standard worm gear clamp?
A: Single bolt clamps (Super Clamps) are designed for applications requiring much higher tightening torques. They provide a more powerful and uniform seal, making them essential for heavy-duty suction hoses and high-pressure reinforced lines.
Q: Can these clamps be used in marine or corrosive environments?
A: Yes, for corrosive environments, we recommend our W4 (304 Stainless Steel) or W5 (316 Stainless Steel) versions, which provide maximum rust protection while maintaining high mechanical strength.
Q: Are the edges of the band safe for my hoses?
A: Absolutely. Our single bolt clamps feature outward-rolled edges specifically designed to prevent any cutting or chafing of the hose, ensuring long-term hose integrity even under extreme pressure.
