1/2"-13 Hex Jam Nut, Grade 8, Coarse Thread, Zinc Yellow Cr+6 Finish

The 1/2"-13 hex jam nut is manufactured from high‑strength Grade 8 steel to deliver secure, long‑lasting locking performance in demanding applications. Its thin jam‑nut profile is ideal for tight‑clearance or double‑nut assemblies, while the coarse thread allows for fast installation and strong holding power. The zinc yellow Cr+6 finish adds corrosion resistance and clear visual identification, making it well suited for automotive, industrial, and heavy‑equipment environments.
