A1: American type hose clamps feature a perforated band design where the screw threads engage with clean punched rectangular slots, providing a secure and adjustable connection.
A2: For marine and saltwater environments, W5 (316 Stainless Steel) is recommended as it offers the maximum corrosion resistance.
A3: Yes, these worm drive clamps are widely used for securing fuel, oil, and air lines in automotive and industrial machinery due to their stable torque performance.
A4: Free torque is the force required to turn the screw without a load, while Breaking torque is the maximum force the clamp can withstand before the band or housing fails.
A5: Yes, as a direct factory, we can stamp custom logos, material codes, and clamping ranges on the band, and provide sizes not listed in the standard table.
A6: The standard bandwidth for this series is 12.7 mm (1/2"), which provides a balanced clamping force for a wide variety of applications.
