The Simpson Strong-Tie MCW Grade 55 Reducing Rod Coupler Nuts are engineered to provide a secure, high-strength connection between threaded rods and anchor bolts of differing diameters. Designed for structural applications, these coupler nuts allow for seamless transitions between mismatched thread sizes, making them an essential solution for retrofit jobs, field modifications, and complex anchoring systems.

Manufactured from zinc plated carbon steel, the MCW reducing coupler nuts offer dependable corrosion resistance for interior and light exterior environments. Their Grade 55 strength ensures reliable load transfer in demanding applications, while precision threading delivers consistent engagement and easy installation. Ideal for contractors, engineers, and DIY builders, these couplers help maintain structural integrity without the need for custom fabrication.

Key Features:

• Reduces Thread Sizes: Connects threaded rods to anchor bolts of different diameters for versatile jobsite use
• Grade 55 Strength: Designed for structural performance and reliable load transfer
• Zinc Plated Carbon Steel: Provides corrosion resistance for indoor and light exterior applications
• Precision Threading: Ensures consistent fit and strong engagement across all compatible sizes
• Time-Saving Solution: Eliminates the need for custom fabrication or additional adapters

Applications:

• Connecting threaded rod to anchor bolts with mismatched diameters
• Structural anchoring systems in concrete and masonry
• Retrofit and repair applications requiring size transitions
• Commercial and residential construction projects
• Mechanical, electrical, and plumbing (MEP) support systems

Installation:

• Select the appropriate reducing coupler nut based on the required thread size transition
• Thread the anchor bolt into the larger diameter side of the coupler
• Attach the threaded rod to the smaller diameter side
• Tighten securely using appropriate tools to ensure full thread engagement
• Verify alignment and load requirements before final installation
