The Sacrifice 2-Bolt Nutron Clamp is a big clamp in a small clamp's body. This double clamp features a threaded steel insert that keeps your bolts from stripping, so it can be tightened as much as you need or want. A shim is also included, so the Nutron can be used with both standard  (31.8mm) and oversized bars (34.9mm)  .
