1‑1/2"-12 Hex Jam Nut, Grade 8, Fine Thread, Plain Finish

The 1‑1/2"-12 hex jam nut is manufactured from high‑strength Grade 8 steel for secure locking in precision, high‑load applications. Its fine thread provides increased holding power and precise adjustment, while the thin jam‑nut profile is ideal for tight‑clearance assemblies. The plain finish is best suited for dry, non‑corrosive industrial, automotive, and mechanical environments.
