Slotted Nut, 1-1/4"-7

The 231335 Slotted Nut, 1-1/4"-7 is a heavy-duty castellated nut designed for secure fastening in applications where vibration or movement could cause standard nuts to loosen. Sized for 1-1/4"-7 threads, this slotted nut is typically paired with a cotter pin to lock it in place after tightening. Commonly manufactured from low-carbon steel with a zinc coating for corrosion resistance, it provides dependable performance in demanding mechanical environments—because once tightened, it’s meant to stay that way.
