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

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