1‑1/8"-7 Hex Jam Nut, Grade 8, Coarse Thread, Zinc Yellow Cr+6 Finish

The 1‑1/8"-7 hex jam nut is manufactured from high‑strength Grade 8 steel to deliver 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 holding power. Finished with a zinc yellow Cr+6 coating, it provides enhanced corrosion resistance and easy visual identification for industrial, automotive, and heavy‑equipment environments.
