Title says it all. The clps, that have 2" stamped into the saddle, are NOT 2". If you need to clamp something that is 2", then you need the Walker 1-7/8" clamps. Glad they don't sell bolts. "What do you mean those half inch x 3.5" cap screws were the wrong size? You must have misunderstood, that's not the size of the bolt. We meant that they were for things that were 3.5"x 1/2"...." WTF I mean, I get , it's for clamping a pipe, that is specifically the diameter of exhaust pipe, and hats been expanded large enough for a 2" pipe to fit inside. But honestly, that's not a valid,measurement, not even close.
