Review on 🔧 Swpeet 92-Piece Assorted Kit of Zinc Plated Mini Fuel Injection Line Style Hose Clamps - Ideal for Automotive, Agriculture, Plant, and Construction Applications by Jesse Hughes

The screw part of the clamp is poorly made, it's not actually a flare nut but a solid cheap metal hex piece. Also, the size of the nut head is 7mm. None of my SAE or metric drivers would fit it, so I had to dig out a 7mm socket and driver. They're probably good enough for vacuum lines, but I wouldn't use them for fuel. I was desperate to complete the work I had or I would have returned it. You get what you pay for.
