PXZ1200195 Greenfield Manufacturing 5/8″‑11 × (...)

The Greenfield Manufacturing 5/8″‑11 × 1‑1/2″ serrated hex flange bolt combines a standard hex head with a built‑in flange washer and serrated bearing surface. This design provides increased load distribution, eliminates the need for a separate washer, and resists loosening under vibration. Manufactured from carbon steel with a zinc‑plated finish, it offers moderate corrosion resistance for indoor and light outdoor applications. The coarse 5/8‑11 UNC thread ensures strong mechanical engagement for structural, automotive, and industrial assemblies requiring high clamping force.

5/8″‑11 coarse thread × 1‑1/2″ zinc‑plated serrated hex flange bolt designed for secure fastening with integrated washer face and vibration resistance.
