Review on Versatile Stainless Steel Duct Clamps by John Hall

After using hose clamps on projects for a long time, I found that these clamps have thread issues. A 7mm metric screw moves the clamp band and distorts the Phillips gripper holes. This contributed to the slow clamping as it felt stiff. I use 5/16 bolt sizes and a smooth flow when installing or removing. I was able to complete my project. Pinch protection for the refrigerant line harness, but I'm not a fan of products from this manufacturer.
