Hex Coupling Nut, A563 A, Zinc Cr+3 (Inch)
Hex Coupling Nuts A563 Grade A Zinc Cr+3 are low-carbon steel fasteners designed to join two pieces of threaded rod or other male-threaded components for extended length connections. Manufactured in accordance with ASTM A563 Grade A specifications, these coupling nuts feature a standard hexagonal shape for easy wrenching and reliable torque application. The Zinc Cr+3 (trivalent chrome) plating provides excellent corrosion resistance, a bright silver-blue finish, and a more environmentally friendly alternative to hexavalent coatings.
Engineered for strength and precision, A563 Grade A Zinc Cr+3 Hex Coupling Nuts deliver secure and durable connections in construction, equipment assembly, and structural applications. The zinc plating enhances rust protection and appearance, making these coupling nuts suitable for indoor and moderately corrosive environments. Commonly used to connect threaded rods, anchor bolts, or studs, these nuts ensure proper alignment and consistent thread engagement while maintaining high fastening integrity and ease of installation.
