1‑1/2"-12 Hex Jam Nut, Grade 8, Fine Thread, Zinc Yellow Cr+6 Finish

The 1‑1/2"-12 hex jam nut is manufactured from high‑strength Grade 8 steel to provide secure, long‑lasting locking performance in heavy‑duty, precision applications. Its fine thread delivers increased holding power and accurate adjustment, while the thin jam‑nut profile makes it ideal for tight‑clearance or double‑nut assemblies. The zinc yellow Cr+6 finish enhances corrosion resistance and provides easy visual identification, making it well suited for industrial, automotive, and heavy‑equipment environments.
