These are not flimsy. They're like channel lock pliers. You can choose 3 notch sizes so that the handles are always close to each other when you need to apply force. These fit my 50hp tractor filter, and my tiny generator filter. Caution, these will put dents into the filter when force is applied. So only use them to remove a filter, or you will damage the new filter.I like these a lot, especiallyfor the price. I do recommend them.
