So I bought a set of about 12 HF end cap wrenches. I may have used one in the 5 years since I bought it. I normally use a band wrench. Trying to get the hydraulic filter off my Bobcat. Its on very tight and not enough leverage for a band wrench. So I pull out the HF set, its a large filter but the largest is too big and next one down is too small. Wrap some tape around the filter and tap on the end cap wrench. The small spot welded plate with a 3/8" square hole falls off. Cheap spot welds I guess. Now to look around for other options.
