Hex Coupling Nuts, A563 A, Plain (Inch)
Hex Coupling Nuts A563 Grade A Plain are low-carbon steel fasteners designed for joining two pieces of threaded rod or other male-threaded components. Manufactured to ASTM A563 Grade A specifications, these coupling nuts feature a standard hexagonal body for easy wrenching and provide reliable, full-length thread engagement. The plain (uncoated) finish allows for smooth assembly and is ideal for indoor or non-corrosive environments where surface protection is not required.
Engineered for alignment and extension applications, A563 Grade A Plain Hex Coupling Nuts offer dependable tensile strength and precision threading for structural, construction, and general-purpose fastening. Commonly used in tension rod systems, machinery assemblies, and anchor bolt extensions, these nuts provide a secure connection and maintain thread alignment. Their low-carbon steel composition allows for good weldability and machinability, while the plain finish is suitable for secondary coatings or custom surface treatments.
