Spec Sheet
Thread Size Compatibility
This jam nut fits 3/4-16 in Left-Hand threaded rods, studs, and rod ends. Left-hand nuts thread counter-clockwise to tighten and are used on the left-hand end of a threaded rod assembly. Confirm thread size and hand before ordering, since left-hand and right-hand jam nuts are not interchangeable and mixing them will not lock the assembly.
