1‑1/2"-6 Hex Jam Nut, Grade 8, Coarse Thread, Plain Finish

This 1‑1/2"-6 hex jam nut is made from high‑strength Grade 8 steel for reliable locking in heavy‑duty, high‑load applications. Designed with a thin jam‑nut profile and coarse threads, it is ideal for tight‑clearance assemblies where maximum strength and vibration resistance are required. The plain finish is best suited for dry, non‑corrosive industrial, automotive, and mechanical environments.
