Hex Coupling Nuts, A563 A, Hot Dipped Galvanized (Inch)
Hex Coupling Nuts A563 Grade A Hot-Dipped Galvanized are low-carbon steel fasteners designed to connect two threaded rods or other male-threaded components for extended-length applications. Manufactured in accordance with ASTM A563 Grade A specifications, these nuts feature a standard hexagonal body for easy wrenching and consistent torque application. The hot-dipped galvanized coating provides a heavy zinc layer that delivers superior corrosion resistance, making these coupling nuts ideal for outdoor, structural, and exposed environments.
Built for strength and long-lasting performance, A563 Grade A Hot-Dipped Galvanized Hex Coupling Nuts offer dependable thread engagement and enhanced protection against rust and weathering. The thick zinc coating formed during the galvanization process ensures excellent durability and bonding for extended service life in harsh or humid conditions. Commonly used in construction, bridgework, and utility installations, these coupling nuts provide secure alignment and strong, corrosion-resistant connections for critical structural applications.
