9/16"-12 Hex Jam Nut, Grade 8, Coarse Thread, Plain Finish

This 9/16"-12 hex jam nut is manufactured from high‑strength Grade 8 steel for reliable locking in high‑load and high‑vibration applications. The thin jam‑nut design and coarse thread make it ideal for tight‑clearance assemblies where strength and security are critical. The plain finish is best suited for dry, non‑corrosive automotive, industrial, and mechanical environments.
