NH 46520 Shear Bolts, 1/4"-20 x 1-1/2" Hex Head

The NH 46520 Shear Bolt is a 1/4"-20 × 1-1/2" hex head bolt designed to protect New Holland hay balers by shearing under excessive load. Acting as a mechanical safety point, this bolt is intended to break when machinery experiences overload conditions, preventing damage to more expensive drivetrain components. Built to the proper size and strength for baler applications, it helps keep equipment protected and downtime to a minimum—because replacing a small shear bolt is a lot better than replacing a gearbox.
