These shear bolts are Grade 2 square-head 3/8"-16 × 2-3/4" fasteners designed specifically for New Holland baler shear-point applications, helping protect driveline components by failing at the intended load. They fit Ford/New Holland hay baler models 166, 66, and Super 66, and cross-reference to multiple common part numbers for easier matching. In other words: they’re meant to break—so the expensive parts don’t.
