7/8"-9 Hex Jam Nut, Grade 8, Coarse Thread, Zinc Yellow Cr+6 Finish

The 7/8"-9 hex jam nut is manufactured from high‑strength Grade 8 steel to provide reliable locking performance in heavy‑duty, high‑load applications. Its thin jam‑nut profile is ideal for tight‑clearance or double‑nut assemblies, while the coarse thread allows for quick installation and strong engagement. The zinc yellow Cr+6 finish enhances corrosion resistance and provides easy visual identification, making it well suited for automotive, industrial, and heavy‑equipment environments.
